Chip Handling Guide
Precaution against Electrostatic Discharge
When using semiconductor devices, ensure that the environment is protected against static electricity:
1. Wear antistatic clothes and use earth band.
2. All objects that are in direct contact with devices must be made up of materials that do not produce static
electricity.
3. Ensure that the equipment and work table are earthed.
4. Use ionizer to remove electron charge.
Contamination
Do not use semiconductor products in an environment exposed to dust or dirt adhesion.
Temperature/Humidity
Semiconductor devices are sensitive to:
Environment
Temperature
SAMSUNG

cn / louishan at 2015.01.13
Humidity
High temperature or humidity deteriorates the characteristics of semiconductor devices. Therefore, do not store or
use semiconductor devices in such conditions.
Mechanical Shock
Do not to apply excessive mechanical shock or force on semiconductor devices.
Chemical
Do not expose semiconductor devices to chemicals because exposure to chemicals leads to reactions that
deteriorate the characteristics of the devices.
Light Protection
In non- Epoxy Molding Compound (EMC) package, do not expose semiconductor IC to bright light. Exposure to
bright light causes malfunctioning of the devices. However, a few special products that utilize light or with security
functions are exempted from this guide.
Radioactive, Cosmic and X-ray
Radioactive substances, cosmic ray, or X-ray may influence semiconductor devices. These substances or rays
may cause a soft error during a device operation. Therefore, ensure to shield the semiconductor devices under
environment that may be exposed to radioactive substances, cosmic ray, or X-ray.
EMS (Electromagnetic Susceptibility)
Strong electromagnetic wave or magnetic field may affect the characteristic of semiconductor devices during the
operation under insufficient PCB circuit design for Electromagnetic Susceptibility (EMS).

3.4 Internal ROM Boot
The chip has built-in 20 KB ROM. It is possible to set Internal ROM address to 0th address by setting
CfgBOOTMODE of System Configuration to "3 to 7". After Reset, CPU executes instruction fetched from 0th
address of the Internal ROM. Internal ROM has a code supporting various Booting methods. This ROM code
executes User Bootcode by reading it through various media and loading it to specific memory. This Booting
method is defined as internal ROM Booting (which is, from now on, called iROMBOOT).
iROMBOOT uses internal SRAM for storing stack or data. Therefore it is possible for the content of internal SRAM
to change after iROMBOOT is executed.
3.4.1 Features
Supports five booting modes: SPI Serial EEPROM BOOT, UART BOOT, USBBOOT, SDHCBOOT and
NANDBOOT with Error Correction
Supports CPU Exception Vector Redirection for OS systems without using MMU.
Supports Fast Power Control: Set VDDPWRON and VDDPWRON_DDR as High.
3.4.2 System Configuration for the Internal ROM booting
iROMBOOT supports 5 Booting modes such as USBBOOT, UART BOOT, SPI Serial EEPROM BOOT,
SDHCBOOT, and NANDBOOT with Error Correction. Every Booting mode supports various booting methods by
referring to Reset states from SD[15:0] and SDEX[7: 0]. Table 3-5 shows System configuration for each Booting
mode.

3.4.3 USB BOOT
iROMBOOT can load User Boot code via USB to memory and execute this code, which Booting method is called
USBBOOT.
3.4.3.1 Features
Supports Full speed or High Speed USB connection.
Uses the USB Bulk transfer.
Supports 64 bytes for Full speed and 512 bytes for High speed as Max packet size.
3.4.3.2 Operation
SAMSUNG

Figure 3-2
USBBOOT Operation
USB Host Program should transfer User boot code by using bulk transfer through EP2 of USB Device. The max
packet size is changeable according to USB connection speed at Endpoint. In Full speed connection, USB Host
Program can transfer the maximum 64 bytes as one packet and, in High speed connection, the maximum 512
bytes as one packet. USB Host Program should transfer the data packet of even size even though it can transfer
the same packet as the max size or the packet smaller than the max size.
USBBOOT writes User Boot code from USB Host Program and USBBOOT executes User Boot code by changing
PC to 0xFFFF0000 after it receives User Boot code size of 16 KB.

The SDHCBOOT Booting process is as follows.
eMMC Booting: SDHCBOOT executes eMMC Booting in case that CfgSDHCBM is 1.
When CfgEMMCBM is "1", Normal eMMC Booting is executed, and when CfgEMMCBM is "0", Alternate
eMMC Booting is executed.
For eMMC Booting, SDHCBOOT always uses 4-bit data bus. Therefore BOOT_BUS_WIDTH of
EXT_CSD should be set to "1." And BOOT_ACK of EXT_CSD should be set to "0" because BOOT_ACK
is not available for eMMCBooting.
Normal SDMMC Booting is processed when no Data is transferred from Card in 1 second.
512 bytes first transferred from Card are not used.
512 bytes secondly transferred from Card are used.
User Boot code transferred from Card is loaded to internal SRAM to be executed.

NANDBOOTEC can correct the errors which occur in User Boot code stored in NAND flash memory. Whenever
NANDBOOTEC reads User Boot code from NAND flash memory by 512 bytes or 1024 bytes, it gets to know
whether any error of Data exists or not by using Error detection function of H/W BCH decoder included in MCU-S.
In case of any error in Data, the maximum 24 or 60 errors can be corrected through H/W Error Correction. If Error
Correction fails, Booting with USB Boot mode.

3.4.6.2 Exception Vector Redirection
Exception Handler of ARM CPU should exist from 0th address by 4 byte one after the other. User generally places
the routine jumping to User's Exception Handler to the Exception Handler existing from 0th address. However, in
case of iROMBOOT, User's Exception Handler is impossible to set at 0th address because ROM exists at
0thaddress. CPU Exception can be processed by mapping the arbitrary memory to 0th address when MMU is
being used. However iROMBOOT provides the function redirecting Exception Handler for the System not using
MMU.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
iROMBOOT uses 32 bytes from the lowest address of internal SRAM as User Exception Vector Table. When
Exception occurs, ROM Exception Handler in iROMBOOT lets PC jump to the address of User Exception Handler
taken from User Exception Vector Table. Therefore Exception can be processed even at Physical address system
by User's setting the address of User Exception Handler to User Exception Vector Table present in internal SRAM
and that is equal to High Vector Address.

NANDBOOTEC can correct the maximum 24 errors in User Boot code 512 bytes and Parity 39 bytes or maximum
60 errors in User Boot code 1024 bytes and Parity 105 bytes. Therefore, by generating Parity 39 bytes at every
512 bytes of User Boot code, User should write the parity information to ECC Sector. For NANDBOOTEC, the
number of Parity information varies according to the size of User Boot code. It is recommended to refer to the
description of NANDBOOTEC about the site in which Parity information should be located.

The clock of the S5P4418 is roughly divided into FCLK, HCLK, MCLK, BCLK and PCLK are used for the ARM
CPU core, AXI bus peripherals and APB bus peripherals, respectively. In addition, BCLK is the clock for the
S5P4418 system bus. MCLK is the clock for SDRAM memory. The 2-PLL of the S5P4418 is called PLL0 and
PLL1, respectively. The 2-PLL and EXTCLK are used to generate the above clocks (i.e. FCLK, HCLK, PCLK,
BCLK, MCLK). All PLLs are designed to operate with an X-TAL input of 24MHz.

If the Pre Divider receives a Fin input of 24 MHz, it divides the Fin with "P". After that, Phase Frequency Detector
(PFD) compares the difference between Fin/P (Reference Clock) and Fvco/M (Feedback Clock). The amplitude of
the voltage varies depending on the difference of the values compared between Fin/P and Fvco/M. If the
reference clock is faster feed back block, the Voltage Controlled Oscillator (VCO) increases in proportion to the
difference. If the reference clock is delayed than the feed clock, VCO is decreased, and it generates an Fvco
clock. That is because VCO is a voltage value and plays the role of controlling the clock speed to be faster or
slower. At this point, the voltage value is determined by the difference of the values compared between the
reference clock and the feedback clock. If the Fvco is not a desired clock, the feedback is recreated through the
Main Divider and compared in PFD. These steps are repeated until the reference clock and the feedback clock
become equal. If proper FVCO is out, the final Fout clock is created as the divide value(s) of a Post Scaler.
Finally, the desired clock frequency is determined by the p, m and s values.
As described above, Fout can be variously set by Fin and p/m/s values and the equation to specify p/m/s values is
as follows: (Note that all PLL0/1/2/3 indicate Fout. Equation may vary for each case.)
PLL x = ( m x Fin)/(p x 2s)
(x = 0,1,2,3, m = MDIV, p = PDIV, s = SDIV = 0, 1, 2, 3)
The range of the MDIV and PDIV values for PLL x are as follows:
Range of MDIV Value: 64 ≤ MDIV ≤ 1023
Range of PDIV Value: 1 ≤ PDIV ≤ 63

4.4.1.5 PLL Power Down
The S5P4418 supports PLL Power Down mode to minimize power consumption. For example, if all system clocks
are generated with PLL0 and PLL1 does not need to be used. Therefore, power does not need to be supplied to
the PLL1. In such a case, the S5P4418 switches PLL1 into power down mode to reduce the power consumption.
However, PLL0 cannot enter to the power down mode. PLL0 power down can be achieved by writing "1" to the
CLKMODEREG0.PLLPWDN1.
4.4.2 Change PLL Value
When CPU want to change the PLL divider value, The PLL Change Bit (PWRMODE.CHGPLL bit) must be set to 1
after setting the PLL Setting Reset (PLLSETREG0, PLLSETREG1) to appropriate value.
Power management and Clock Controller blocks up the clock supplied to internal controllers because PLLs are
unstable when PLL divider value is changed. After locking time, these blocks supply clock. CPU must check
whether the blocks run or stop such as STOP mode.

SAMSUNG

cn / louishan at 2015.01.13
In the IDLE mode, since the power and clocks are supplied to all blocks except for the CPU clock, power
consumption can be reduced a bit. To enter to IDLE mode, the PWRMODE.IDLE Register should be set as "1". In
IDLE Mode, the CPU clock is not supplied, but the power is normally supplied and PLLs operate normally.
Wake-Up Source can use all the S5P4418 interrupts that can be generated by the Interrupt controller: GPIO
Interrupt, Alive GPIO Interrupt, External Interrupt and RTC Interrupt. The interrupt for the Wake-Up Source should
be enabled before entering to the IDLE Mode. The CPU returns to the previous status immediately after it is
woken up in IDLE Mode.

4.5.2.2 STOP Mode
In STOP mode, the clock is not supplied to all bocks including the ARM Core, because the PLL also does not
operate in the clock controller if the clock is not supplied to all blocks. However, the S5P4418 converts DRAM into
Self Refresh mode to protect memory data before entering to STOP mode. Like IDLE mode, the
PWRMODE.STOP should be set as "1" to enter to STOP mode.
The Wake Up source is slightly limited in STOP mode. The available Wake Up sources are RTC Interrupt, Alive
GPIO Interrupt, etc. The Wake Up source is limited because the clock is not supplied to all the other blocks except
for the power manager and RTC block. Since the RTC block uses a separate power and clock, only interrupts by
the RTC clock can be used as a Wake Up source.
Unlike with IDLE mode, all PLLs stop when the system is woken up in STOP mode so that the system cannot
return to the previous status, immediately. Therefore, the Wake Up time is about 70 ms longer than that of IDLE
mode to stabilize the internal PLLs.

Power Down Mode Sequence
Figure 4-9 shows the sequence to enter the Power Down mode and the Wake Up procedure. First, the Wake Up
source selects a desired event (interrupt) and specifies the attribute of the event. If the Wake up Source is GPIO,
the setting is changed into Input and the Pending Clear is performed. In addition, the status to detect that an event
(interrupt) is specified and Software Reset Enb is set as False for the worst case (If the Software Reset Enb
switch is not implemented in terms of Hardware, False does not need to be specified). Finally, the system enables
the relevant interrupt (if an interrupt is used) and enters a Power Down mode.
In this Power Down mode, the S5P4418 a waits a Wake Up event (interrupt). If the Wake Up event (Interrupt)
occurs, the S5P4418 returns to normal mode and clears the relevant interrupt pending in terms of Software.

As shown in Figure 4-10, Power Manager use different clock. Since RTC-clock is always supplied to Power
Manager Block, the PADs can be used as a Wake Up Source.
The description of the Wake Up procedures in Power Down mode is as follows:
Wake Up in IDLE Mode
During IDLE mode, clock and the power for the other blocks are supplied normally except CPU clock. Therefore,
the input received in GPIO is applied to the interrupt controller and wakes up the CPU.
Wake Up in STOP Mode
In STOP mode, all clocks except for the RTC clock are not supplied (PLL and XTI are included). The interrupt
controller does not operate in STOP mode. At this time, if a signal is entered to Power Manager, the power
manager wakes up the clock manager, first. As a result of this Wake Up, all clocks, such as the PLL and PCLK,
BCLK, MCLK and FCLK, are enabled and supplied to the CPU and the whole system. In other words, the system
is woken up. The Wake Up time is about 70 ms longer than that of IDLE mode to stabilize the PLLs.

4.6 Reset Generation
4.6.1 Power on Reset Sequence
Power management block has the reset generation block. The reset generation block uses the nPORST which is
sampled at RTC clock (32.768 kHz). And the RTC clock is used as main clock for power management. So Even if
the RTC Function is not used, the RTC clock must be supplied.
Figure 4-11 shows the clock and reset behavior during the power-on reset sequence.

4.6.4 Software Reset and GPIO Reset
S5P4418 supports Software Reset that CPU can reset itself with Software reset. To generate Software Reset,
SWRSTENB bit must be set to 1 before setting PWRMODE.SWRST bit. Software Reset mode does not need the
time for stabilization clock because the software reset is requested in stable state differently from power on reset.
S5P4418 supports user defined GPIO Reset. The Power management block generates reset when the AliveGPIO
pad defined as GPIO Reset source is asserted or de-asserted. The AliveGPIO pad is used as GPIO Reset source
are defined at Wakeup Source Register. The GPIORSTENB bit set to 1 enables the AliveGPIO Reset source
feature.
4.6.5 Watchdog Reset
The Watchdog timer block is used to resume the controller operation whenever it is disturbed by malfunctions
such as system error, etc. When power management block detects the event from watchdog timer, it generates
exactly the same reset as power on reset because the watchdog reset event occurs in malfunctions and unknown
state.

4.8 AXI BUS
ARM PL301 (AXI3 BUS interconnect) provides programmable function for AXI BUS and which includes QoS and
Programmable Round-Robin.
4.8.1 Programmable Quality of Service (ProgQoS)
The QoS scheme works by tracking the number of outstanding transactions, and when a specified number is
reached, only permits transactions from particular, specified masters.
The QoS scheme only provides support for slaves that have a combined acceptance capability, such as the
PrimeCell Dynamic Memory Controller (PL340).
The QoS scheme has no effect until the AXI bus matrix calculates that, at a particular MI, there are a number of
outstanding transactions equal to the value stored in the QoS tidemark Register. It then accepts transactions only
from slave ports specified in the QoS access control Register. This restriction remains until the number of
outstanding transactions is again less than the value stored in the QoS tidemark Register.
It is recommended that you assign low MI numbers to MIs that require QoS support. This approach aligns well
with the cyclic priority scheme because MIs that require QoS support are typically those that can be considered
high-ranking slaves. See the PrimeCell High-Performance Matrix (PL301) Technical Reference Manual.
Below Figure shows the implementation for an interconnection that supports two masters and one slave.

4.8.2 Arbitration scheme
You can configure each MI separately to have an arbitration scheme that is a programmable or fixed Round-robin
(RR) scheme.
The AW and AR channels have separate arbiters and can be programmed, if applicable, and interrogated
separately through the APB programming interface, but both AW and AR channels are configured identically.
Because the AW and AR channels are arbitrated separately, an MI can permit simultaneous read and write
transactions from different SIs.
The arbitration mechanism registers the arbitration decision for use in the subsequent cycle. An arbitration
decision taken in the current cycle does not affect the current cycle.
If no SIs are active, the arbiter adopts default arbitration, that is, the highest priority SI. If this occurs and then the
highest priority interface becomes active in the same cycle as, or before any other SI, then this does not constitute
a grant to an active SI and the arbitration scheme does not change its state as a result of that transfer.
If a QoS provision is enabled and active, only a subset of SIs are permitted to win arbitration, and it cannot be
guaranteed that the default arbitration is among these. In these circumstances, no transaction is permitted to use
the default arbitration, and arbitration must occur when there is an active SI.
4.8.2.1 RR schemes
In these schemes, you can choose, at design time:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
the number of slots that are used
the SI to which they are allocated
their order.
There must be at least one slot per connected SI and there can be up to 32 slots. By allocating multiple slots for
an SI, you can allocate access to the slave, on average, in proportion to the number of slots. If the slots are
appropriately ordered, this can also reduce the maximum time before a grant is guaranteed. The SI associated
with a slot can be interrogated from the APB programming interface and can be changed if the programmable RR
scheme is chosen.
Whenever arbitration is granted to an active SI, the slots are rotated so that the slot currently in the highest priority
position becomes the lowest, and all other slots move to a higher priority but maintain their relative order. This
means that if an SI is the highest priority active SI, but is not the highest priority interface, then it continues to win
the arbitration until it becomes the highest priority interface, and then the lowest priority interface subsequently.

Because the arbitration value is registered, the arbitration decision made in this cycle is used in the next cycle.
This means that if the SI that currently holds the arbitration is still the highest priority active SI in this cycle, wins
the arbitration again regardless of whether or not it is active in the next cycle as shown by the status of M3 in
stages A, B, and C of below Figure 4-15.

DREX-1 supports pause feature through external ports
called "PAUSE_REQ" and "PAUSE_ACK". When
PAUSE_ACK is set to low, DREX-1 guarantees that
there will be no requests issued to the DRAM until the
external port PAUSE_REQ is driven to high. This
feature is used for switching the clock frequency of the
memory interface.
Clock frequency change of memory can be applied

DREX-1 has an input signal named ca_swap. If this
signal is driven to 1, the DFI interface's address signals
will have its bit locations reversed. (addr[9] and addr[0]
will be swapped, addr[8] and addr[1] will be swapped,
etc) The purpose of this signal is for supporting different
packaging solutions, so that the system level designer
can choose among one of the modes depending on the
routing requirement of the packaging or the PCB using
the SoC with DREX-1. Please take care since driving
the wrong ca_swap value may render the whole SoC
unusable!

The pin has to be tied to a valid value. This pin helps
maintain backward compatibility of the controller for
the HSIC feature per port. This pin is quasi static, that
is, it doesn't change during a session and has to be
tied to stable value (preferably) from power-on. If this
pin is external to the core through registers, it must be
stable before the enumeration of the port begins
(before the AHB reset).
This signal is implemented in one of two ways.
If heterogeneous ports is not selected during core
Consultant configuration, this bussed input port
should be driven to the same value
homogeneously externally to the controller.
If heterogeneous ports is selected during core
Consultant configuration, its width is still

in contiguous order, and each strap pin can
independently and asynchronously enable HSIC

4.9.1.4.1 Programmable Quality of Service (ProgQoS)
Address map
The register space for the MIs starts at 0x400 and extends to 0x7FC.
Each MI that is configured to support QoS filtering contains the registers at the following offsets:
0x0: QoS tidemark Register
0x4: QoS access control Register.
When more than one MI with QoS support is included then the MI number controls the register address offset for
that MI.
Qos tidemark Register
You can program this with the number of outstanding transactions that are permitted before the QoS scheme
becomes active.
If a value is written to this register that is larger than the combined acceptance capability of the attached slave,
then the QoS scheme never becomes active for this MI. If a value of 0 is written to this register, then the QoS
scheme is turned off for this MI. This behavior ensures that it is impossible to block all transactions completely by
accidental mis-programming.
If you access a QoS tidemark Register for an MI that has not been configured to support QoS then the HPM
ignores writes and reads are undefined.
SAMSUNG

cn / louishan at 2015.01.13
Qos access control Register
A 1 in any bit of this register indicates that the SI corresponding to the bit position is permitted to use the reserved
slots of the connected combined acceptance capability of the slaves.
The maximum value that you can write to this register is 2^^ -1.
NOTE: If you attempt to write a value containing 1s in positions that do not correspond to SIs, then these bits are ignored and
are not set in the register.
Changes to these values occur on the first possible arbitration time after they are written.
If you access a QoS access control Register for an MI that has not been configured to support QoS then the HPM
ignores writes and reads are undefined.

4.9.1.4.2 Arbitration control
The arbitration schemes for the AR channel and AW channel are set when you configure the HPM, and they
control the arbitration scheme for these channels when the HPM exits from reset. However, the HPM enables you
to change the AR channel and AW channel arbitration schemes by using the APB SI on the HPM to write to the
arbitration control registers.
The HPM provides two arbitration control registers per MI, one for the AR channel and one for the AW channel.
They operate and are programmed in the same way.
As the address map does not have sufficient space for each value to be addressable separately, some addressing
information is encoded in the write data when updating values. When reading registers the extra addressing
information is supplied by a preliminary write command before the read command.
NOTE: When a master interface has connections to only one slave interface its operation is much simpler and as a result the
arbitration mechanism is removed. If you attempt to configure or interrogate the arbitration mechanism for such a
master interface, all writes are ignored, and each read returns zero.
Programmable RR arbitration scheme
The following sections describe how to program and read the values for the programmable RR arbitration scheme:

When the programmable RR scheme is selected for a master interface then each of its arbitration slots can have

NOTE: No protection is imposed when you program the slots in the programmable RR arbitration scheme. So it is possible
for you to remove a slave interface from all the slots which would make that slave interface inaccessible. However, if
the mechanism for programming the configuration registers uses the interconnect, it is possible to make the
configuration mechanism itself inaccessible.
Reading configuration values
You must perform a write followed by a read operation to the same address. The write transfer sets the slot
number to be read for that master interface. The following read operation returns the slave interface that is
associated with that slot number.
Table 4-17 lists the bit assignments of the preliminary write operation.

System L2 Cache (PL-310 L2C)
6.1 Overview
The addition of an on-chip secondary cache, also referred to as a Level 2 or L2 cache, is a recognized method of
improving the performance of ARM-based systems when significant memory traffic is generated by the processor.
By definition a secondary cache assumes the presence of a Level 1 or primary cache, closely coupled or internal
to the processor.
Memory access is fastest to L1 cache, followed closely by L2 cache. Memory access is typically significantly
slower with L3 main memory.

6 System L2 Cache (PL-310 L2C)
6.2 Features
The cache controller features:
Slave and master AMBA AXI interfaces designed for high performance systems.
Lockdown format C supported, for data and instructions.
Lockdown by line supported.
Lockdown by master ID supported.
L2 cache available size can be 16 KB to 8 MB, depending on configuration and the use of the lockdown
registers.
Fixed line length of 32 bytes, eight words or 256 bits.
Interface to data RAM is byte writable.
Supports all of the AXI cache modes:
Write-through and write-back
Read allocate, write allocate, read and write allocate.
Force write allocate option to always have cacheable writes allocated to L2 cache, for processors not
supporting this mode.
Normal memory non-cacheable shared reads are treated as cacheable non-allocatable. Normal memory noncacheable shared writes are treated as cacheable write-through no write-allocate. There is an option, Shared
Override, to override this behavior.
Critical word first line fill supported.
Pseudo-Random, or round-robin victim selection policy. You can make this deterministic with use of lockdown
registers.
Four 256-bit Line Fill Buffers (LFBs), shared by the master ports. These buffers capture line fill data from main
memory, waiting for a complete line before writing to L2 cache memory.
Two 256-bit Line Read Buffers (LRBs) for each slave port. These buffers hold a line from the L2 memory for a
cache hit.
Three 256-bit Eviction Buffers (EBs). These buffers hold evicted lines from the L2 cache, to be written back to
main memory.
Three 256-bit Store Buffers (STBs). These buffers hold bufferable writes before their draining to main
memory, or the L2 cache. They enable multiple writes to the same line to be merged.
Software option to enable exclusive cache configuration.
Configuration registers accessible using address decoding in the slave ports.
Address filtering in the master ports enabling redirection of a certain address range to one master port while
all other addresses are redirected to the other one.

6.4.1 L2 Cache User Configure
System L2 Cache Base Address: Base Address: 0xCF000000
Turn off and Turn on L2C:
Turn off offset 0x100 (Base Address + 0x100) set to 0
Turn on offset 0x100 (Base Address + 0x100) set to 1
Early Write Response:
The AXI protocol specifies that the write response can only be sent back to an AXI master when the last write
data has been accepted. This optimization enables the L2C-310 to send the write response of certain write
transactions as soon as the store buffer accepts the write address. This behavior is not compatible with the
AXI protocol and is disabled by default. You enable this optimization by setting the Early BRESP Enable bit in
the Auxiliary Control Register, bit[30]. The L2C-310 slave ports then send an early write response only if the
input signal AWUSERSx[11], x = 0 or 1, is set to 1'b1 for the corresponding write transaction.
6.4.2 Initialization Sequence
As an example, a typical cache controller start-up programming sequence consists of the following register
operations:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
1. Write to the Auxiliary, Tag RAM Latency, Data RAM Latency, Pre-fetch, and Power Control registers using a
read-modify-write to set up global configurations:
Associativity, Way Size
latencies for RAM accesses
allocation policy
Pre-fetch and power capabilities.
2. Secure write to the Invalidate by Way, offset 0x77C, to invalidate all entries in cache:
Write 0xFFFF to 0x77C
Poll cache maintenance register until invalidate operation is complete.
3. Write to the Lockdown D and Lockdown I Register 9 if required.
4. Write to interrupt clear register to clear any residual raw interrupts set.
5. Write to the Interrupt Mask Register if you want to enable interrupts.
6. Write to Control Register 1 with the LSB set to 1 to enable the cache.
If you write to the Auxiliary, Tag RAM Latency, or Data RAM Latency Control Register with the L2 cache enabled,
this results in a SLVERR. You must disable the L2 cache by writing to the Control Register 1 before Writing to the
Auxiliary, Tag RAM Latency, or Data RAM Latency Control Register.

DMA
8.1 Overview
The DMA Controller (DMAC) is an Advanced Microcontroller Bus Architecture (AMBA) block that connects to the
Advanced High-performance Bus (AHB). There is an AHB slave interface for programming the DMAC and 2 AHB
masters for data transfer. There are two DMAC in S5P4418 and each DMAC has eight channels, which can buffer
up to 4 words each. Each channel can transfer data through either of the AHB Master interfaces with the
programmed data width and endianness. The DMAC supports 16 DMA requestors, and generates individually
maskable interrupts for Terminal count and transfer error for each channel.

8 DMA
8.2 Features
16 DMA channels. Each channel can support a unidirectional transfer.
16 DMA requests. The DMAC provides 16 peripheral DMA request lines.
Single DMA and burst DMA request signals. Each peripheral connected to the DMAC can assert either a burst
DMA request or a single DMA request. You set the DMA burst size by programming the DMAC.
Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and peripheral-to-peripheral transfers.
Scatter or gather DMA support through the use of linked lists.
Hardware DMA channel priority. Each DMA channel has a specific hardware priority. DMA channel 0 has the
highest priority and channel 7 has the lowest priority. If requests from two channels become active at the
same time, the channel with the highest priority is serviced first.
AHB slave DMA programming interface. You program the DMAC by writing to the DMA control registers over
the AHB slave interface.
Two AHB bus masters for transferring data. Use these interfaces to transfer data when a DMA request goes
active.
Incrementing or non-incrementing addressing for source and destination.
Programmable DMA burst size. You can program the DMA burst size to transfer data more efficiently. The
burst size is usually set to half the size of the FIFO in the peripheral.
Internal four word FIFO per channel.
Supports eight, 16, and 32-bit wide transactions.
Big-endian and little-endian support. The DMAC defaults to little-endian mode on reset.
Separate and combined DMA error and DMA count interrupt requests. You can generate an interrupt to the
processor on a DMA error or when a DMA count has reached 0. This is usually used to indicate that a transfer
has finished. There are three interrupt request signals to do this:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
DMACINTTC signals when a transfer has completed.
DMACINTERR signals when an error has occurred.
DMACINTR combines both the DMACINTTC and DMACINTERR interrupt request signals. You can use
the DMACINTR interrupt request in systems that have few interrupt controller request inputs.
Interrupt masking. You can mask the DMA error and DMA terminal count interrupt requests.
Raw interrupt status. You can read the DMA error and DMA count raw interrupt status prior to masking.
Test registers for use in block and integration system level testing.
Identification registers that uniquely identify the DMAC. An operating system can use these to automatically
configure itself.

8.4 Functional Description
8.4.1 Software Considerations
You must take into account the following software considerations when programming the DMAC:
There must not be any write-operation to Channel registers in an active channel after the channel enable is
made HIGH. If you must reprogram any DMAC channel parameters, you must reprogram after disabling the
DMAC channel.
If the source width is less than the destination width, the TransferSize value multiplied by the source width
must be an integral multiple of the destination width.
When the source peripheral is the flow controller and the source width is less than the destination width, the
number of transfers that the source peripheral performs, before asserting a DMACLSREQ *or *DMACLBREQ,
must be so that the number of transfers multiplied by the source width is an integral multiple of the destination
width. If this case is violated, the data can get stuck and lost in the FIFO causing UNPREDICTABLE results.
You can abort the transfer by disabling the relevant DMAC channel.
You must not program the SrcPeripheral and DestPeripheral bit fields in the DMACCxConfig Register with any
value greater than 15. See Channel Configuration Registers.
The SWidth and DWidth bit fields in the DMACCxControl Register must not indicate more than a 32-bit wide
peripheral. See Channel Control Registers.
After the software disables a channel by clearing the Channel Enable bit in the DMACCxConfig Register, see
Channel Configuration Registers, it must re-enable the bit only after it has polled a 0 in the corresponding
DMACEnbldChns Register bit, see 'Enabled Channel Register. This is because the actual disabling does not
immediately happen with the clearing of Channel Enable bit. You must accommodate the latency of the on
going AHBburst.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The LLI field in the DMACCxLLIReg Register must not indicate an address greater than 0xFFFFFFF0,
otherwise the four-word LLI burst wraps over at 0x00000000 and the LLI data structure is not in contiguous
memory locations. See Channel Linked List Item Registers.
When the transfer size programmed in the DMAC is greater than the depth of the FIFO in a source or
destination peripheral, you must only program the DMAC for non-incrementing address generation.
A peripheral is expected to deassert any DMACSREQ, DMACBREQ, DMACLSREQ, or DMACLBREQ signals
on receiving the DMACCLR signal irrespective of the request the DMACCLR was asserted in response to.
This is because DMACCLR is not specific to a single-request signal, DMACSREQ, or burst-request signal,
DMACSBEQ. The handshaking of DMACCLR is achieved with a logical OR of all the DMA requests in the
DMAC.
NOTE: It is illegal for a peripheral to give a new DMACSREQ or DMACBREQ signal while DMACCLR is HIGH.

8 DMA
If you program the TransferSize field in the DMACCxControl Register, see Channel Control Registers, as
zero, and the DMAC is the flow controller, the TransferSize field has no meaning in other flow-control modes,
then the channel does not initiate any transfers. It is your responsibility to disable the channel by writing into
the channel enable bit of the DMACCxConfig Register and reprogramming the channel again.
You must not run the normal read-write tests on the DMACCxControl Register, see Channel Control
Registers, because the TransferSize field is not a typical write and read-back register field. While writing, the
TransferSize bit-field is like a control register because it determines how many transfers the DMAC performs.
However, during read-back, TransferSize behaves like a status register because it returns the number of
remaining transfers in terms of source width. So when TransferSize is read back, it returns the number of
destination-transfer-completed stored in a separate counter called TrfSizeDst multiplied by a factor. The same
physical register is not being written into and read from, and normal write and read-back tests are not
applicable.
In the destination flow control mode, with peripheral-to-peripheral transfer, if sufficient data is present in the
channel FIFO to service a DMACLSREQ or DMACLBREQ request raised by a destination peripheral without
requiring data to be fetched from the source peripheral, then the source peripheral is issued a *DMACTC.
For destination flow controlled case, peripheral-to-peripheral transfer, with DWidth < SWidth, the number of
data bytes requested by the destination peripheral must be an integral multiple of Swidth expressed in bytes.
If you do not ensure this, then the DMAC might fetch more data from the source peripheral than is required.
This can result in data loss.
At the end of accesses corresponding to low-priority channels, an IDLE cycle is inserted on the AHB bus to
enable other masters to access the bus. This ensures that a low-priority channel does not monopolize the
bus. It does, however, mean that the bus might be occupied by transactions corresponding to a low priority for
up to 16 cycles in the worst case. This applies to all transfer configurations, including memory-to-memory
transfers.

8.4.2 Programmer's Model
8.4.2.1 About the programmer's Model
The DMAC enables the following types of transactions:
memory-to-memory
memory-to-peripheral
peripheral-to-memory
peripheral-to-peripheral.
Each DMA stream is configured to provide unidirectional DMA transfers for a single source and destination.
For example, a bidirectional serial port requires one stream for transmit and one for receive. The source and
destination areas can each be either a memory region or a peripheral, and you can access them through the
same AHB master, or one area by each master.
The base address of the DMAC is not fixed, and can be different for any particular system implementation.
However, the offset of any particular register from the base address is fixed.
Register fields
The following applies to the registers that the DMAC uses:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
You must not access reserved or unused address locations because this can result in unpredictable behavior
of the device.
You must write reserved or unused bits of registers as zero, and ignore them on read unless otherwise stated
in the relevant text.
A system or power-on reset resets all register bits to logic 0 unless otherwise stated in the relevant text.
All registers support read and write accesses unless otherwise stated in the relevant text. A write updates the
contents of a register, and a read returns the contents of the register.
You can only access registers defined in this document using word reads and word writes, unless otherwise
stated in the relevant text.

8.4.2.2 Programming the DMAC
Enabling the DMAC
Enable the DMAC by setting the DMA Enable, E, bit in the DMAC Configuration Register. See Configuration
Register.
Disabling DMAC
To disable the DMAC:
1. Read the DMACEnbldChns Register and ensure that you have disabled all the DMA channels. If any
channels are active, see disabling a DMA channel.
2. Disable the DMAC by writing 0 to the DMA Enable bit in the DMAC Configuration Register. See 'Configuration
Register.
Enabling a DMA channel
Enable the DMA channel by setting the Channel Enable bit in the relevant DMA channel Configuration Register.
See Channel Configuration Registers.
NOTE: You must fully initialize the channel before you enable it. Additionally, you must set the Enable bit of the DMAC before
you enable any channels.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
Disabling a DMA channel
You can disable a DMA channel in the following ways:
1. Write directly to the Channel Enable bit.
NOTE: You lose any outstanding data in the FIFOs if you use this method.
2. Use the Active and Halt bits in conjunction with the Channel Enable bit.
3. Wait until the transfer completes. The channel is then automatically disabled.
Disabling a DMA channel and losing data in the FIFO
Clear the relevant Channel Enable bit in the relevant channel Configuration Register.
See Channel Configuration Registers. The current AHB transfer, if one is in progress, completes and the channel
is disabled.
NOTE: You lose any data in the FIFO.

Disabling a DMA channel without losing data in the FIFO
To disable a DMA channel without losing data in the FIFO:
1. Set the Halt bit in the relevant channel Configuration Register. See Channel Configuration Registers. This
causes any subsequent DMA requests to be ignored.
2. Poll the Active bit in the relevant channel Configuration Register until it reaches0. This bit indicates whether
there is any data in the channel that has to be transferred.
3. Clear the Channel Enable bit in the relevant channel Configuration Register.
Setting up a new DMA transfer
To set up a new DMA transfer:
1. If the channel is not set aside for the DMA transaction:
Read the DMACEnbldChns Register and determine the channels that are inactive. See Enabled Channel
Register.
Choose an inactive channel that has the necessary priority.
2. Program the DMAC.
Halting a DMA channel
SAMSUNG
Confidential
cn / louishan at 2015.01.13
Set the Halt bit in the relevant DMA channel Configuration Register. The current source request is serviced. Any
subsequent source DMA requests are ignored until the Halt bitis cleared.
Programming a DMA channel
To program a DMA channel:
1. Choose a free DMA channel with the necessary priority. DMA channel 0 has the highest priority and DMA
channel 7 has the lowest priority.
2. Clear any pending interrupts on the channel you want to use by writing to the DMAC IntTCClear and DMAC
IntErrClr Registers. See Interrupt Terminal Count Clear Register and Interrupt Error Clear Register. The
previous channel operation might have left interrupts active.
3. Write the source address into the DMACCxSrcAddr Register. See Channel Source Address Registers.
4. Write the destination address into the DMAC CxDestAddr Register. See Channel Destination Address
Registers.
5. Write the address of the next LLI into the DMACCxLLI Register. See Channel Linked List Item Registers. If
the transfer consists of a single packet of data, you must write 0 into this register.
6. Write the control information into the DMACCxControl Register. See ChannelControl Registers.
7. Write the channel configuration information into the DMACCxConfiguration Register. See 'Channel
Configuration Registers. If the Enable bit is set, then the DMA channel is automatically enabled.

8.4.2.6 Scatter/gather
Scatter/gather is supported through the use of linked lists. This means that the source and destination areas do
not have to occupy contiguous areas in memory. You must set the DMACCxLLI Register to 0 if you do not require
scatter/gather. For more information about scatter/gather DMA, see Appendix B DMA Interface.
Linked list items
An LLI consists of four words. These words are organized in the following order:
1. DMACCxSrcAddr
2. DMACCxDestAddr
3. DMACCxLLI
4. DMACCxControl
NOTE: The DMACCx Configuration Channel Configuration Register is not part of the LLI.
Programming the DMAC for scatter/gather DMA
To program the DMAC for scatter/gather DMA:
1. Write the LLIs for the complete DMA transfer to memory. Each LLI contains four words:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
source address
destination address
pointer to next LLI
control word.
The last LLI has its linked list word pointer set to 0.
1. Choose a free DMA channel with the required priority. DMA channel 0 has the highest priority and DMA
channel 7 the lowest priority.
2. Write the first LLI, previously written to memory, to the relevant channel in the DMAC.
3. Write the channel configuration information to the channel configuration register and set the Channel Enable
bit. The DMAC then transfers the first and then subsequent packets of data as each LLI are loaded.
4. An interrupt can be generated at the end of each LLI depending on the Terminal Count bit in the
DMACCxControl Register. If this bit is set, an interrupt is generated at the end of the relevant LLI. You must
then service the interrupt request, and you must set the relevant bit in the DMACIntTCClear Register to clear
the interrupt. If so, you must service this interrupt request and you must set the relevant IntTCClear bit in the
DMACIntTCClr Register to clear the interrupt request interrupt.

Scatter/gather through linked list operation.
A series of linked lists define the source and destination data areas. Each LLI controls the transfer of one block of
data, and then optionally loads another LLI to continue the DMA operation, or stops the DMA stream. The first LLI
is programmed into the DMAC.
The data to be transferred described by an LLI, referred to as the packet of data, usually requires one or more
DMA bursts, to each of the source and destination.
Figure 8-2 shows an example of an LLI. A rectangle of memory must be transferred to a peripheral. The
addresses of each line of data are given, in hexadecimal, at the left-hand side of the figure. The LLIs describing
the transfer are to be stored contiguously from address 0x20000.
SAMSUNG

cn / louishan at 2015.01.13
Figure 8-2
LLI Example
The first LLI, stored at 0x20000, defines the first block of data to be transferred. This is the data stored between
addresses 0x0A200 and 0x0AE00:
source start address 0x0A200
destination address set to the destination peripheral address
transfer width, word, 32-bit
transfer size, 3072 bytes, 0xC00
source and destination burst sizes, 16 transfers
next LLI address, 0x20010.
The second LLI, stored at 0x20010, defines the next block of data to be transferred:
source start address 0x0B200
destination address set to the destination peripheral address
transfer width, word, 32-bit
transfer size, 3072 bytes, 0xC00
source and destination burst sizes, 16 transfers
next LLI address, 0x20020.

A chain of descriptors is built up, each one pointing to the next in the series. To initialize the DMA stream, the first
LLI, 0x20000, is programmed into the DMAC. When the first packet of data has been transferred, the next LLI is
automatically loaded.
The final LLI is stored at 0x20070 and contains:
source start address 0x11200
destination address set to the destination peripheral address
transfer width, word, 32-bit
transfer size, 3072 bytes, 0xC00
source and destination burst sizes, 16 transfers
next LLI address, 0x0.
Because the next LLI address is set to zero, this is the last descriptor, and the DMA channel is disabled after
transferring the last item of data. The channel is probably set to generate an interrupt at this point to indicate to the
ARM processor that the channel can be reprogrammed.
8.4.2.7 Interrupt requests
Interrupt requests can be generated when an AHB error is encountered, or at the end of a transfer, terminal count,
after all the data corresponding to the current LLI has been transferred to the destination. The interrupts can be
masked by programming the relevant bits on the relevant DMACCxControl and DMACCxConfiguration Channel
Registers.
SAMSUNG

cn / louishan at 2015.01.13
Interrupt Status Registers are provided. They group the interrupt requests from all the DMA channels prior to
interrupt masking, DMACRawIntTCStatus, DMACRawIntErrorStatus, and after interrupt masking,
DMACIntTCStatus, DMACIntErrorStatus.
The DMACIntStatus Register combines both the DMACIntTCStatus and DMACIntErrorStatus requests into a
single register to enable the source of an interrupt to be found quickly. Writing to the DMACIntTCClear or the
DMACIntErrClr Registers with a bit set HIGH enables selective clearing of interrupts.
The DMAC provides two interrupt request connection schemes. See Interrupt controller connectivity. The simplest
connection scheme has a combined error and end of transfer complete interrupt request. To find the source of an
interrupt, you must read both the DMACIntStatus and DMACIntTCStatus Registers.
For faster interrupt response, you can use an alternate connection scheme. This scheme uses separate interrupt
requests for the error and transfer complete requests. Read either the DMACIntTCStatus or DMACIntErrorStatus
Registers to find the source of an interrupt.

Combined terminal count and error interrupt sequence flow
When you use the *DMACINTR *interrupt request:
1. You must wait until the combined interrupt request from the DMAC goes active. Assuming the interrupt is
enabled in the interrupt controller and in the processor, the processor branches to the interrupt vector address
and enters the interrupt service routine.
2. You must read the interrupt controller Status Register and determine whether the source of the request was
the DMAC.
3. You must read the DMACIntStatus Register to determine the channel that generated the interrupt. If more

Terminal count interrupt sequence flow
When the separate, DMACINTTC and DMACINTERR, interrupt requests are used:
1. You must wait until the terminal count DMA interrupt request goes active. Assuming the interrupt is enabled in
the interrupt controller and in the processor, the processor branches to the interrupt vector address and enters
the interrupt service routine.
2. You must read the interrupt controller Status Register to determine if the source of the interrupt request was
the DMAC asserting the DMACINTTC signal.
6. You must read the DMACIntTCStatus Register to determine the channel that generated the interrupt. If more
than one request is active, it is recommended that you service the highest priority channel first.
4. You must service the interrupt request.
5. You must write a 1 to the relevant bit in the DMACIntTCClear Register to clear the interrupt request.

The read/write DMACSync Register, with address offset of
0x034, enables or disables synchronization logic for the
DMA request signals.
The DMA request signals consist of:
• DMACBREQ[15:0]
• DMACSREQ[15:0]
• DMACLBREQ[15:0]
• DMACLSREQ[15:0].
A bit set to 0 enables the synchronization logic for a

NOTE: It is illegal for a peripheral to give a new
DMACSREQ or DMACBREQ signal while DMACCLR is
HIGH.
NOTE: You must use synchronization logic when the
peripheral generating the DMA request runs on a different
clock to the DMAC. For peripherals running on the same
clock as the DMAC, disabling the synchronization logic
improves the DMA request response time. If necessary,
synchronize the DMA response signals, DMACCLR and
DMACTC, in the peripheral.

Transfer size. A write to this field sets the size of the

value counts down from the original value to zero, and
so its value indicates the number of transfers left to
complete. A read from this field provides the number
of transfers still to be completed on the destination

does not give useful information because by the time

This causes the current AHB transfer, if one is in

9 Interrupt Controller
Interrupt Controller
9.1 Overview
64 interrupt sources from internal peripherals, including the DMA controller, UART, I2C and GPIO, etc. supply
requests to an Interrupt Controller.
An FIQ or an IRQ (interrupt requests) are signaled by the Interrupt Controller to CPU. After arbitrating multiple
requests from internal peripherals and GPIO, the Controller requests an interrupt.
The hardware arbitration logic decides the interrupt arbitration process and the results are recorded in the interrupt
pending registers.
9.2 Features
SAMSUNG

cn / louishan at 2015.01.13
The interrupt controller is responsible for:
support for 64 IRQ interrupts
2 channels, each channel processes 32 IRQ interrupts and has each AHB bus.
IRQ and FIQ generation
AHB mapped for faster interrupt response
software interrupt generation

9.3 Block Diagram
The interrupt controller has two channels. Each channel has 32 interrupt sources. The interrupt request logic
receives the interrupt requests from the peripheral and combines them with the software interrupt requests. It then
masks out the interrupt requests which are not enabled, and routes the enabled interrupt requests to either IRQ
Status or FIQ Status. Figure 9-1 shows a block diagram of the interrupt request logic in each channel.

9.4 Programming sequence
9.4.1 Interrupt Flow Sequence Using AHB
The following procedure shows the sequence for the IRQ interrupt flow:
An IRQ interrupt occurs.
The ARM processor branches to the IRQ interrupt vector
Stack the workspace so that IRQ interrupts can be re-enabled later.
Perform a dummy read to the VICADDRESS Register to set up priority status control in the VIC.
Read the VICIRQSTATUS Register and determine which interrupt sources have to be service.
Execute the ISR. At the beginning of the ISR, the interrupt of the processor can be re-enabled so that a higher
priority interrupt can be serviced.
Clear the requesting interrupt in the peripheral, or write to the VICSOFTINTCLEAR Register if the request was
generated by a software interrupt.
Disable the interrupt on the processor and restore the workspace.
Write to the VICADDRESS Register. This clears the respective interrupt in the internal interrupt priority
hardware.
Return from the interrupt. This re-enables the interrupts.

10.3 Functional Description
10.3.1 Watchdog Timer Operation
Figure 10-1 shows the functional block diagram of the watchdog timer. The watchdog timer uses only PCLK as its
source clock. The PCLK frequency is prescaled to generate the corresponding watchdog timer clock, and the
resulting frequency is divided again.
Figure 10-1
Watchdog Timer Block Diagram
The prescaler value and the frequency division factor are specified in the watchdog timer control (WDTCON)
8
register. Valid prescaler values range from 0 to 2 -1. The frequency division factor can be selected as 16, 32, 64
or 128.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
Use the following equation to calculate the watchdog timer clock frequency and the duration of each timer clock
cycle:
t_watchdog = 1/(PCLK/(Prescaler value + 1)/Division_factor)

10.3.2 WTDAT & WTCNT
Once the watchdog timer is enabled, the value of watchdog timer data (WTDAT) register cannot be automatically
reloaded into the timer counter (WTCNT). In this reason, an initial value must be written to the watchdog timer
count (WTCNT) register, before the watchdog timer starts.
10.3.3 Consideration of Debugging Environment
When the MDIRAC-III is in debug mode Embedded ICE, the watchdog timer must not operate. The watchdog
timer can determine whether or not it is currently in the debug mode from the CPU core signal (DBGACK signal).
Once the DBGACK signal is asserted, the reset output of the watchdog timer is not activated as the watchdog
timer is expired.

10.3.4.2 Watchdog Timer Control (WTCON) Register
The WTCON register allows the user to enable/disable the watchdog timer, select the clock signal from 4 different
sources, enable/disable interrupts, and enable/disable the watchdog timer output.
The Watchdog timer is used to resume restart in mal-function after its power on, if controller restart is not desired,
the Watchdog timer should be disabled.
If the user wants to use the normal timer provided by the Watchdog timer, enable the interrupt and disable the
Watchdog timer.
10.3.4.3 Watchdog Timer Data (WTDAT) Register
The WTDAT register is used to specify the time-out duration. The content of WTDAT cannot be automatically
loaded into the timer counter at initial watchdog timer operation. However, using 0x8000(initial value) will drive the
first time_out. In this case, the value of WTDAT will be automatically reloaded into WTCNT.
10.3.4.4 Watchdog Timer Count (WTCNT) Register
The WTCNT register contains the current count values for the watchdog timer during normal operation. Note that
the content of WTDAT register cannot be automatically loaded into the timer count register when the watchdog
timer is enabled initially, so the WTCNT register must be set to initial value before enabling it.
10.3.4.5 Watchdog Timer Interrupt (WTCLRINT) Register
The WTCLRINT register is used to clear the interrupt. Interrupt service routine is responsible for clearing the
relevant interrupt after the interrupt service is completed. Writing any values on this register clears the interrupt.
Reading this register is not allowed.

NOTE: As shown in Figure 11-1, the left and right parts of the central dotted line use RTC Power and Normal Power,
separately. The RTC Power Block uses a mercury battery, but the block actually using the mercury battery is the RTC
Counter in the RTC Power Block. The battery life is about five years.
In Figure 11-1, the output in point [A] is applied to the Power Manager or the Interrupt Controller. The output is
applied to the Interrupt Controller in Normal mode and applied to the Power Manager in Power mode.
NOTE: Even if RTC is not used, RTC power and RTC clock should be supplied.

11.4 Functional Description
11.4.1 Backup Battery Operation
As shown in Figure 11-1, since the RTC block uses a separate power source (Coin Battery), the RTC block
operates even when the external power is turned off.
The RTC Logic can be driven by the Backup Battery, which supplies the power through the VDD_RTC pin into the
RTC Block, even if the system power is off. When the system power is off, the interfaces of the CPU and RTC
logic should be blocked and the backup battery only drives the oscillation circuit and the internal 32-bit RTC
counter to minimize power dissipation. In other words, the RTC block can be used as the Wake-Up Source when
the S5P4418 is converted into Power Down mode.
The use of the RTC block as a Wake-Up source requires that the RTCCTRL.ACCESSENB bit is set as "0" before
the system enters Power Down mode. Setting it as "0" is performed to use the RTC as the Wake-Up source even
when the system enters the Power Down Mode. (For detailed information on the Power Down Mode, refer to
Section 4.)
Even if the RTC block is not used, the RTC Clock must be connected to S5P4418 because the RTC clock is used
as the clock for power management operation.
11.4.2 RTC Operation
The RTC generates an alarm signal at a specified time in the Power Down Mode or Normal Operation Mode. In
Normal Operation Mode, the Alarm Interrupt is activated. In Power Down Mode, the Power Management Wake Up
Signal is activated as well as the RTCALARM. The ALARM Time Set register (RTCALARM) determines the
condition of the alarm time setting and the RTCINTENB.ALARMINTENB bit determines the alarm enable/disable
status.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The procedure to generate an alarm interrupt is as follows:
First, write a counter value to the RTCCNTWRITE register. (To this end, the busy status of the
RTCCTRL.RTCCNTWAIT should be checked in advance. The written value is applied to the register after two
32.768 kHz clock cycles.) After that, write the value of the point at which you wish to generate an interrupt to the
RTCALARM register. The RTC counter increases the counter value at intervals of 1 Hz. If the values of the two
registers (RTCCNTWRITE and RTCAKARM registers) become equal when the RTCINTENB.ALARMINTENB bit
is set as "1", an interrupt occurs.
In a similar way, the RTC interrupt is detected in a rising edge of 1 Hz. In this case, the interrupt is generated by
setting the RTCINTENB.RTCINTENB bit as "1".
In addition, The RTCINTENB register contains the Pending Clear function and the Pending Clear is performed by
writing "0".

11 RTC
11.4.3 Accessing the RTC Time Counter Setting/Read Register
To access RTC Time Count Read Register (RTCCNTREAD) and RTC Time Count Setting Register
(RTCCNTWRITE), the RTCCTRL.RTCCNTWRITEENB bit is set to "1" before accessing these register. When the
CPU completes to access these register, the CPU should set the RTCCTRL.RTCCNTWRITEENB bit to "0" to
protect the content of RTC counter from unknown problem in abnormal state. The RTCCNTWRITEENB bit
determines the reflection of the RCCNTWRITE register value to the RTC counter.
11.4.4 Interrupt Pending Register
Only the "READ" function is available for the RTCINTPND register of the S5P4418, but the current pending status
can be read.
Since the RTCINTPND register only has a "READ" function, the Pending Clear function is controlled by the
RTCINTENB register. The Interrupt Pending status is cleared by disabling the relevant interrupt. Therefore, if the
corresponding bit of the RTCINTENB register is set as "1", the relevant interrupt is enabled. If the corresponding
bit is set as "0", the interrupt is disabled and the pending bit is also cleared.
11.4.5 Power Manager Reset Time Control
RTC controls the time when nPWRMANRST (Power Manager Reset) releases from CorePOR. Refer to
RTCCORERSTIMESEL Register for setting the time when nPWRMANRST releases.

12.1 Overview
In the status with eliminating core power supply of S5P4418, some PAD need power supply continuously and
should keep driving PAD with certain value.
For example a bit that controlling STN LCD should keep driving PAD with low in the status with eliminating core
power supply. 32-bit value can be saved in Scratch Register and the saved value maintains in the case of core
power off.
User could on/off the system power by pressing toggle switch and ALIVE performs the necessary functions in
these momentary power controls.
12.2 Features

cn / louishan at 2015.01.13
Alive GPIO PADs are all in/output PAD.
The value of ALIVE Block maintains even in power off of Core Power.
Alive Block does not use clock. To change the control register value, need to program set/reset pin of SRflipflop directly.
Chip sleep mode wake-up source (AliveGPIO, VDDToggle, RTCIRQ)
Power IC Enable.
Supports the PAD Hold function
Scan chain is not inserted to Alive GPIO.

12.3 Power Isolation
12.3.1 Core Power Off
In the case of power off of CoreVDD, Alive Registers maintains its value since Alive VDD keep supplied. Pulldown register connected to nPowerGating performs the function of maintaining control bit of Alive Registers
securely in the interval of core power off or unstable.
12.3.2 Power Gating
The value of set/reset should be kept as low to maintains the value of Alive Registers securely in the case of
power off of CoreVDD. Therefore, it's designed to maintain low value in the case of core power off since
nPowerGating register is connected to pull-down register.

12.4 Alive Registers
All of the Registers except nPowerGating/AliveDetectPending Register of Alive block maintains the value written
in Register when Core power turns off, and are reset when Alive Power turns off. Alive Registers do not have their
own Clock, and these can be read and written when nPowerGating register is "1" (nPowerGating = 1). And
especially, in write mode, Alive Registers can be written by SET/RST (reset) Register. The following is the
example of the Register function according to Register SET/RST.
Alive Registers remains as the former state when Regiser_nameSET == 0, Regiser_nameRST=0
Alive Registers are written as "1" when Regiser_nameSET == 1, Regiser_nameRST=0
Alive Registers are written as "0" write "0" when Regiser_nameSET == 0, Regiser_nameRST=1
Alive Registers are written as "1" when Regiser_nameSET == 1, Regiser_nameRST=1
12.4.1 Alive GPIO Detect Registers
For Alive GPIO input, Alive GPIO Detect Registers can be used as Core Power on, Alive Interrupt, Sleep mode
wakeup source in case of Asynchronous/synchronous detecting mode. And when those events are detected,
ALIVEGPIODETECTPENDREG[n] Register is set to "1". The following are the operating examples according to
Detecting modes.
Ex1) Asynchronous Low Level Detecting
Alive GPIO Detect Registers detect the event when ALIVEGPIOLOWASYNCDETECTMODEREADREG [n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", and AliveGPIO ==0

Alive GPIO Detect Registers detect the event when ALIVEGPIOHIGHASYNCDETECTMODEREADREG [n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", and AliveGPIO[n] == "1"
Ex3) Synchronous Low Level Detecting
Alive GPIO Detect Registers detect the event when ALIVEGPIOLOWSYNCDETECTMODEREADREG [n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", AliveGPIO[n] == "0"
Ex4) Synchronous High Level Detecting
Alive GPIO Detect Registers detect the event when ALIVEGPIOHIGHSYNCDETECTMODEREADREG [n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", AliveGPIO[n] == "1"
Ex5) Synchronous Falling Edge Detecting
Alive GPIO Detect Registers detect the event when ALIVEGPIOFALLDETECTMODEREADREG[n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", and AliveGPIO[n] bit changes from "1" to "0"
Ex6) Synchronous Rising Edge Detecting
Alive GPIO Detect Registers detect the event when ALIVEGPIORISEDETECTMODEREADREG [n] = "1",
ALIVEGPIODETECTENBREADREG[n] = "1", and AliveGPIO[n] bit changes from "0" to "1"

12.5 Momentary Power Control
12.5.1 CoreVDD Powering On
The Core Power can be changed from off-state to on-state by the VDDPWRTOGGLE switch, AliveGPIO
Detecting, RTC interrupt. And in case of Power on, VDDPWRTOGGLE switch, AliveGPIO Detecting, and RTC
interrupt can be processed, after system booting, by setting VDDPWRON_DDR/VDDPWRON Bit. (Power On is
not allowed when Battery Fault occurs.).
12.5.2 CoreVDD Powering Off
The Core Power can be changed from off-state to on-state by clearing VDDPWRON_DDR/VDDPWRON Bit.
Core Block and Alive Block are connected through PowerGating Register, which makes it possible for Alive
Registers to safely sustain their own values even after Core Power turns off with
VDDPWRON_DDR/VDDPWRON Bit cleared.
The following is the example of Chip Power sequence
1. Do not hold the initial Pad state. (nPadHold = 1)
2. Hold the Pad before you turn off the Power. (nPadHold Register = 0)
3. Turn off VDDPWRON
SAMSUNG
Confidential
cn / louishan at 2015.01.13
4. Non-Alive POR is set low after power turns off
5. Power starts to be supplied by pressing toggle switch
6. PAD releases from the hold state when internal POR turns on (which provides the stability for preventing pad
hold from releasing after power turns on)
7. VDDPWRON and PadHold Register should be released simultaneously after system booting.
8. VDDPOWRON should be released.
nPadHoldEnb Register should be set as "0" except Power On Reset.

Sense Mode Timing
When SIGDEV is enabled ("H"), sensing current is occurred. So you should reduce SIGDEV pulse width high
period for power saving.
CS should be set high (enable) and A2, A1, A0 states should be set properly before first SIGDEV rising in
sense mode.
After sense operation, DOUT[] have "0" for un-blown fuse cell and "1" for blown fuse cell.
Sense (read) operation would be performed correctly with timing diagram above. The user who want to have
different timing sequence must have a prior consultation with effuse designer.

13.5 Application Notes
Permitting Over-the-cell routing. In chip-level layout, over-the-cell routing in EFROM_LP is permitted without
any restrictions over Metal-4 layer.
Incomming power bus should be adjusted to guarantee NOT more than 5 % voltage drop at typical-case
current levels.
Reduce resistance (<3 ) between PAD and FSOURCE pin of EFROM_LP.
Connect routing signal to all of the FSOURCE pins.
When using two or more e-fuse sets, FSOURCE line can be shared among e-fuse sets, but program-mode
operation should be applied sequentially. (For example, at first, operate e-fuse0 and then operate e-fuse1 for
program-mode) It applies same during sense-mode, but there is a guideline for multi-sensing, only sensemode.Keep the below rules. Refer to integration guide document for further information.
Allowed maximum resistance can be obtained by 3 /# of 128-bit efuse box.
If customer wants to run multi-sensing,

14.3.2 MCU-S Bank Feature
Latched Addressing
The number of pins that are connected to the outside is ADDR[18:0]. Since, however, the total address of the
MCU-S Bank is 26-bit. ADDR[8:2] and ADDR[25:19] are allotted to the same pin, the system has a structure
in which addresses are output two times. If the system uses ADDR[19] or more, the setting of higher address
(ADDR[25:19]) is possible via System Configuration Pin (CfgSTLATADD). In this event, ADDR[25:19] which is
configured by using external Latch IC first should be latched.

14.3.4 MCU-A Address Mapping
DREX modifies the address of the AXI transaction coming from the AXI slave port into a memory address - chip
select, bank address, row address, column address and memory data width.
To map chip select of memory device to a specific area of the address map, the chip_base and chip_mask bitfields of the MemConfig0 register needs to be set (Refer to Register Descriptions). If chip1 of the memory device
exists, the MemConfig1 register must also be set. Then, the AXI address requested by AXI Masters is divided into
the AXI base address and AXI offset address. The AXI base address activates the appropriate memory chip select
and the AXI offset address is mapped to a memory address according to the bank, row, column number, and data
width set by the MemConfig0/1 and MemControl register.
There are two ways to map the AXI offset address as shown below: 14.2.4.1 linear mapping, 14.2.4.2 interleaved
mapping
14.3.4.1 Linear Mapping
As shown in Figure 14-3 the linear mapping method maps the AXI address in the order of bank, row, column and
width. Since the bank address does not change for at least one bank size, applications that use linear address
mapping have a high possibility to access the same bank.

cn / louishan at 2015.01.13
Figure 14-3
Linear Address Mapping
14.3.4.2 Interleaved Mapping
As shown in Figure 14-4 the interleaved mapping method maps the AXI address in the order of row, bank, column
and width. The difference between above two methods is that the bank and row order is different. For accesses
beyond a row size, interleaved mapping accesses a different bank. Therefore, applications that use interleaved
mapping access numerous banks. It causes better performance but more power consumption Command Arbiter.
Command Arbiter re-arbitrates with the result of Fast Arbiter and Slow Arbiter. In this case, Fast Arbiter is always
processed ahead with fixed method.

14 Memory Controller
14.3.5 Low Power Operation
The controller executes a low power memory operation in five ways as described below. Each feature is
independent of each other and executed at the same time.
14.3.5.1 AXI Low Power Channel
The controller has an AXI low power channel interface to communicate with low power management units such as
the system controller, which makes the memory device go into self refresh mode.
14.3.5.2 Dynamic Power Down
An SDRAM device has an active/pre-charge power down mode. This mode is triggered by de-asserting CKE to
LOW. When any of the banks is open, it enters active power down mode. Otherwise, it enters pre-charge power
down mode.
When the request buffers remain empty for certain number of cycles (PwrdnConfig.dpwrdn_cyc register), DREX-1
changes the memory devices state to active/pre-charge power down automatically. The memory device enters
Active/pre-charge power down mode or Forced pre-charge power down mode according to the SFR setting. The
description of the two power down modes are as follows:
1. Active/pre-charge power down mode: Enter power down w/o considering whether there is a row open or not.
2. Forced pre-charge power down mode: Enter power down after closing all banks.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
When DREX-1 receives a new AXI transaction while memory device is in power down mode, it automatically
wakes up the memory device from power down state and executes in a normal operation state.
14.3.5.3 Dynamic Self Refresh
Similarly to the dynamic power down feature, if the request buffers remain empty for certain number of cycles
(PwrdnConfig.dsref_cyc register), DREX-1 changes the memory device's state to self-refresh mode. Since exiting
power down mode requires many cycles, a longer idle cycle threshold is recommended for dynamic self-refresh
entry than the threshold for dynamic power down.
14.3.5.4 Clock Stop
To reduce the I/O power of the memory device and the controller, it is possible to stop the clock if the LPDDR /
LPDDR2-S4 is in idle mode, or self refresh mode and DDR3 is in self refresh mode. If this feature is enabled, the
controller automatically executes the clock stop feature. In DDR3, clock stop feature must be turn-on and off
considering tCKSRX/tCKSRE/tCKESR timing by software.
14.3.5.5 Direct Command
Use the direct command feature to send a memory command directly to the memory device through the APB3
port. This way, it is possible to force the memory device to enter active/pre-charge power down, self-refresh or
deep power down mode

14.3.6.1.1 LPDDR2/3
The following sequence should be used to initialize LPDDR2 devices. Unless specified otherwise, these steps
are mandatory.
1. To provide stable power for memory device, DREX-1 must assert and hold CKE to a logic low level.
Then apply stable clock.
2. Set the right value to PHY control register0 for LPDDR2/3 operation mode. If read leveling is needed,
check LPDDR2/3 IO calibration MRR data and match it to PHY control register1's ctrl_rlvl_rdata_adj field.
(Refer to PHY manual)
3. Set the PHY for dqs pull down mode. (Refer to PHY manual, PHY control register 14)
4. Set the ConControl. At this moment, assert the dfi_init_start field to high but the aref_en field should be off.
5. Wait for the PhyStatus0.dfi_init_complete field to change to [1[.
6. Set the ConControl. At this moment, de-assert the dfi_init_start field to low and the aref_en field should be off.
7. Set the PhyControl0.fp_resync bit-field to [1] to update DLL information for at least one MPCLK cycle.
8. Set the PhyControl0.fp_resync bit-field to [0].
SAMSUNG
Confidential
cn / louishan at 2015.01.13
9. Set the MemControl and PhyControl0. At this moment, all power down modes including sl_dll_dyn_con
should be off.
10. Set the MemBaseConfig0 register. If there are two external memory chips, set the MemBaseConfig1 register.
11. Set the MemConfig0 register. If there are two external memory chips, also set the MemConfig1 register.
12. Set the PrechConfig and PwrdnConfig registers.
13. Set the TimingAref, TimingRow, TimingData and TimingPower registers according to memory AC parameters.
14. If QoS scheme is required, set the QosControl0 to 15 and QosConfig0 to 15 registers.
15. Set the PHY for LPDDR2/3 initialization. LPDDR2/3 initialization clock period is 18ns to 100ns.
If LPDDR2/3 initialization clock period is 20ns, then follow below steps 16 to 22(refer to PHY manual).

of the read DQS gate (=ctrl_gate_p0/p1). Once this point is identified, the read DQS gate can be adjusted prior to
the DQS, to the approximate midpoint of the read DQS preamble. You can use "GATE Leveling" when using
"DDR3 memory" over 800 MHz.
1. Controller should configure Memory (DDR3) in MPR mode. (Please refer to JEDEC Standard.)
2. Set "lpddr2_addr=20'h208" (=PHY_CON22[19:0]) to issue MR32 during GATE Leveling (LPDDR2/3)
In case of CA swap mode, lpddr2_addr=20'h041 to issue MR32 during GATE Leveling
3. Set Gate Leveling Mode.(1)
Enable "gate_cal_mode" in PHY_CON2[24]
Enable "ctrl_shgate" in PHY_CON0[8]
Set "ctrl_gateduradj[3:0] (=PHY_CON1[23:20]) in the following way.
o
4'b0000" (DDR3, DDR2)
o
4'b1011" (LPDDR3)

4. Memory Controller should assert "dfi_rdlvl_en" and "dfi_rdlvl_gate_en" to do read leveling. (2)
5. Memory Controller should wait until "dfi_rdlvl_resp" is set. (3)
The maximum waiting time will be 20 us. If the any command (the refresh or pre-charge command) is
required within 20 us, please issue those commands before "(1)".
6. Memory Controller should deassert "dfi_rdlvl_en" and "dfi_rdlvl_gate_en" after "dfi_rdlvl_resp" is disabled.
7. Disable DQS pull down mode. (4)
8. Memory Controller should configure Memory (DDR3) in normal mode.

Write DQ Calibration adjusts for the delays introduced by the package, board and on-chip that impact the write
cycle.
1. Set Write Latency (WL) before Write Training(1)
Set "T_wrdata_en" by "WL" in PHY_CON26[20:16].
o
WL is defined as clock cycles between the write command and the first valid rising edge of DQS
2. Memory Controller should issue "Active Command".
3. PHY will keep writing and reading the pattern in "PHY_CON1[15:0]" for Write DQ Calibration according to
the following settings.(2)
The column address should be defined in "lpddr2_addr" in PHY_CON22[19:0](LPDDR2, LPDDR3).
o
"lpddr2_addr[9:0]" correspond to CA[9:0] at the rising edge of CK, and "lpddr2_addr[19:10]" to
CA[19:10] at the falling edge of CK.
o
It should be the "READ" command. For example, lpddr2_addr = 20'h5 if the column address is 11'h0
and bank address is 3'b000. In case of CA swap mode, lpddr2_addr = 20'h204 if the column address
is 11'h0 and bank address is 3'b000.
The column address should be defined in "ddr3_addr" in PHY_CON24[15:0] (DDR3)
o
SAMSUNG

Feature
Hardware ECC generation, detection and indication (software correction) 4/8/16/24/40/60 bit error correction
and detection
Error Detection Code/Error Correction Code (EDC/ECC)
NAND-based MLC flash has error weakness therefore error handling method is required. S5P4418 can
perform EDC (error detecting codes) and ECC (error correction codes) and both based on BCH (BoseChadhuri-Hocquenghem) algorithm.EDC is run by hardware to reduce CPU overload and increase the CPU
performance. In contrast, ECC is run by software. Parity bit is calculated on every 512/1024 byte page.
Syndrome is calculated when each data is read from NAND flash and the value is used in error correction
operation.
Hardware ECC generation reset
This reset is asserted when NAND address or command register is written by any value.
This reset is also asserted when ECCRST bit (NFCONTROL register [11] bit) register is set to 1
This reset initializes NFECCL, NFECCH, NFCNT, NFECCSTATUS, NFSYNDRONE0 to 7 Registers.

15.3 Functional Description
S5P4418 GPIO Pins have an internal pull-up resistance of 100 k.
The current of the pull-up resistance (for VDD = 3.3 V and V (PAD) = 0 V) is listed in the table below:

Most S5P4418 GPIO ports contain the Alternate function (some ports supports up to Alternate Function2). All
GPIO ports should be set as GPIO function or Alternate Function suitable for the user's purposes and this setting
can easily be performed with GPIO registers. In addition, all GPIO pull-up resistances are enabled/ disabled. This
setting operates when the system is fully booted and does not affect the system in initial booting. If there is a value
which needs to be determined in system booting, the value is given by inserting a pull up/down resistance from
outside.
15.3.1 Input Operation
To use GPIO for input, the GPIO function should be selected by setting the relevant bit of the GPIO Alternate
Function Select register as b'00 to select the GPIO function. In addition, the GPIO Input mode should be, also,
selected by the GPIOx Output Enable register (GPIOxOUTENB) as “0”.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
An input signal is detected by selecting a desired detection type with the GPIOx Event Detect Mode register. Four
types of input signal can be detected: Low Level, High Level, Falling edge and Rising edge. The GPIOx Event
Detect Mode registers consist of GPIOx Event Detect Mode register0 (GPIOxDETMODE0) and GPIOx Event
Detect Moderegister1 (GPIOxDETMODE1).
To use interrupt, set the GPIOx Interrupt Enable Register (GPIOxINTENB) as “1”.
The GPIOx Event Detect Register (GPIOxDET) enables checking the generation of an event via GPIO and may
be used as the Pending Clear function when an interrupt occurs.
When the GPIOx PAD Status Register (GPIOxPAD) is set as GPIO Input mode, the levelof the relevant GPIOx
PAD can be checked.
The Open drain pins (GPIOB[7:4] and GPIOC[8]) operate in Input mode only when the GPIOx Output register
(GPIOxOUT) is set as “1”. The Open drain pins are operated by the GPIOx Output Register (GPIOxOUT) even if
the GPIOx Output Enable register (GPIOxOUTENB) is set as Input mode.

15.3.2 Output Operation
To use GPIO for output, the GPIO function should be selected by setting the relevant bit of the GPIOx. Alternate
Function Select register should be set as b'00 to select the GPIO function. In addition, the GPIOx Output mode
should also be selected by setting the GPIOx Output Enable register as "1".
If you set a desired output value (low level: "0", high level: "1") with the GPIOx Output Register (GPIOxOUT), the
value is reflected to the corresponding bit.
The Open drain pins (GPIOB[7:4] and GPIOC[8]) operate in output mode only when the GPIOx Output register
(GPIOxOUT) is set as "0". The Open drain pins are operated by the GPIOx Output Register (GPIOxOUT) even if
the GPIOx Output Enable register(GPIOxOUTENB) is set as Input mode.
15.3.3 Alternate Function Operation
Among the 151 GPIO pins of the S5P4418, most GPIO pins have an Alternate function. However, the Alternate
function and the GPIO function should not be used simultaneously. Therefore, Alternate Function1 and Alternate
Function2 are operated by setting the corresponding bits of the GPIOx Alternate Function Select register as b'01
and b'10, respectively.

Reset Value
DMA always attempts to burst as specified in PBL each
time it starts a Burst transfer on the host bus. PBL can be
programmed with permissible values of 1, 2, 4, 8, 16, and
32. Any other value results in undefined behavior. When
USP is set high, this PBL value is applicable only for Tx
DMA transactions.
If the number of beats to be transferred is more than 32,
then perform the following steps:
Set the PBLx8 mode.
Set the PBL.
For example, if the maximum number of beats to be
transferred is 64, then first set PBLx8 to 1 and then set
PBL to 8. The PBL values have the following limitation:
The maximum number of possible beats (PBL) is limited
by the size of the Tx FIFO and Rx FIFO in the MTL layer
and the data bus width on the DMA. The FIFO has a
constraint that the maximum beat supported is half the
depth of the FIFO, except when specified.
Alternate Descriptor Size
When set, the size of the alternate descriptor increases to
32 bytes (8 DWORDS). This is required when the
Advanced Timestamp feature or the IPC Full Checksum
Offload Engine (Type 2) is enabled in the receiver. The
enhanced descriptor is not required if the Advanced
Timestamp and IPC Full Checksum Offload Engine (Type

When this bit is set, the transmit FIFO controller logic is reset

operation is complete. The Operation Mode register should
not be written to until this bit is cleared. The data which is
already accepted by the MAC transmitter is not flushed. It is
scheduled for transmission and results in underflow and runt
frame transmission.

The flush operation is complete only when the Tx FIFO is
emptied of its contents and all the pending Transmit Status of
the transmitted frames are accepted by the host. In order to
complete this flush operation, the PHY transmit clock

mode.
If the MAC is configured for 1000 Mbps operation or if the
Jumbo frame mode is enabled in the 10 or 100 Mbps
mode, the threshold for deferral is 155,680 bits times.
Deferral begins when the transmitter is ready to transmit,
but it is prevented because of an active carrier sense
signal (CRS) on GMII or MII.
The defer time is not cumulative. For example, if the
transmitter defers for 10,000bit times because the CRS
signal is active and then the CRS signal becomes inactive,
the transmitter transmits and collision happens. Because
of collision, the transmitter needs to back off and then
defer again after back off completion. In such a scenario,
the deferral timer is reset to 0 and it is restarted.
When this bit is reset, the deferral check function is
disabled and the MAC defers until the CRS signal goes
inactive. This bit is applicable only in the half-duplex mode

In the half-duplex mode, when this bit is set (and TFE is
set), then backpressure is asserted by the MAC. During
backpressure, when the MAC receives a new frame, the
transmitter starts sending a JAM pattern resulting in a
collision. This control register bit is logically O Red with the
mti_flowctrl_iinput signal for the backpressure function.
When the MAC is configured for the full-duplex mode, the

Block Diagram of Mobile Storage Host
Figure 17-1 illustrates the block diagram of Mobile Storage Host.
Bus Interface Unit (BIU): Provides AMBA AHB/APB and DMA interfaces for register and data read/writes
Card Interface Unit (CIU): Takes care of SD_MMC_CEATA protocols and provides clock management.
The BIU provides the host interface to the registers. It also provides the data FIFO through the Host Interface Unit
(HIU). Additionally, it provides independent data FIFO access through a DMA interface. You can configure host
interface as an AMBA APB slave interface.
The IDMAC is responsible for exchanging data between FIFO and the host memory. A set of IDMAC registers is
accessible by host for controlling the IDMAC operation through the AMBA APB slave interface.
The Mobile Storage CIU controls the card-specific protocols. Within CIU, the command path control unit and data
path control unit interface with the controller to the command and data ports of the SD_MMC_CEATA cards. The
CIU alos provides clock control.

17.2.1.1 Clock Phase Shifter
SD/MMC card receives DATA/CMD with card clock from the host controller. To synchronize the clock and
DATA/CMD, it is required that the clock delay is inserted to the Tx/Rx clock path. For this to happen, the logic is
added to the design as illustrated in the Figure 17-2. And clock selection can be done with CLKSEL register at the
end of this Section.
Figure 17-2
Block Diagram of Mobile Storage Host
This clock phase shifter makes 0, 90, 180, 270 phase shifted clocks for Tx/Rx respectively. To make 50 MHz
phase shifted clock, SDCLKIN should be 100 MHz.

18.2 Functional Description
When a PPM signal rising edge or a falling edge is detected, the 16-bit counter is reset after storing the 16-bit
counter value to the PPMLOWPERIOD register or the PPMHIGHPERIOD register. If a falling edge is detected,
the counter value is stored at the PPMHIGHPERIOD register and then the counter is reset. If a rising edge is
detected, the counter value is stored at the PPMLOWPERIOD register and then the counter is reset. If the high or
the low period is too long to be measured by the 16-bit Counter, an Overflow interrupt occurs. Therefore the IPRemo on input signal should be checked and an appreciate PPL clock value should be specified to prevent the
occurrence of Overflow interrupts.

19 Pulse Width Modulation (PWM) Timer
Pulse Width Modulation (PWM) Timer
19.1 Overview
These timers can be used to generate internal interrupts to the ARM subsystem. In addition, Timers 0, 1, 2, and 3
include a PWM function (Pulse Width Modulation) which can drive an external I/O signal. The PWM for timer 0 has
a optional dead-zone generator capability, which can be utilized to support a large current device. Timer 4 is only
an internal timer with no output pins.
The Timers are normally clocked off of a divided version of the APB-PCLK. Timers 0 and 1 share a programmable
8-bit prescaler that provides the first level of division for the PCLK. Timer 2, 3, and 4 share a different 8-bit
prescaler. Each timer has its own, private clock-divider that provides a second level of clock division (prescaler
divided by 2, 4, 8, or 16). Alternatively, the Timers can also select a clock source from an external pin, except
Timer 4. Timers 0 and 1 can select the external clock TCLK0. Timers 2 and 3 can select the external clock
TCLK1. Timer 4 operates with APB-PCLK only.
Each timer has its own 32-bit down-counter which is driven by the timer clock. The down-counter is initially loaded
from the Timer Count Buffer register (TCNTBn). When the down-counter reaches zero, the timer interrupt request
is generated to inform the CPU that the timer operation is completed. When the timer down-counter reaches zero,
the value of corresponding TCNTBn can be automatically reloaded into the down-counter to start the next cycle.
However, if the timer stops, for example, by clearing the timer enable bit of TCONn during the timer running mode,
the value of TCNTBn will not be reloaded into the counter.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The Pulse Width Modulation function (PWM) uses the value of the TCMPBn register. The timer control logic
changes the output level when the down-counter value matches the value of the compare register in the timer
control logic. Therefore, the compare register determines the turn-on time (or turn-off time) of a PWM output.
The TCNTBn and TCMPBn registers are double buffered to allow the timer parameters to be updated in the
middle of a cycle. The new values will not take effect until the current timer cycle completes.
A simple example of a PWM cycle is shown in the figure below.

1. Initialize the TCNTBn with 160 (50+110) and the TCMPBn with 110.
2. Start Timer by setting the start bit and manual update bit off. The TCNTBn value of 160 is loaded into the
down counter, the output is driven low.
3. When down counter counts down to the value in the TCMPBn register (110), the output is changed from low
to high
4. When the down counter reaches 0, the interrupt request is generated.
5. At the same time the down counter is automatically reloaded with TCNTBn, which restarts the cycle.

19.4.3 Auto-Reload and Double Buffering
The Timers have a double buffering feature, which can change the reload value for the next timer operation
without stopping the current timer operation. So, although the new timer value is set, a current timer operation is
completed successfully.
The timer value can be written into TCNTBn (Timer Count Buffer register) and the current counter value of the
timer can be read from TCNTOn (Timer Count Observation register). If TCNTBn is read, the read value is not the
current state of the counter but the reload value for the next timer duration.
The auto-reload is the operation, which copies the TCNTBn into TCNTn when TCNTn reaches 0. The value,
written into TCNTBn, is loaded to TCNTn only when the TCNTn reaches to 0 and auto-reload is enabled. If the
TCNTn is 0 and the auto-reload bit is 0, the TCNTn does not operate any further.

The result of the following procedure is shown in Figure 19-7.
1. Enable the auto-reload feature. Set the TCNTBn as 160(50+110) and the TCMPBn as 110. Set the manual
update bit and inverter bit(on/off). The manual update bit makes the TCNTn, TCMPn set to the value of
TCNTBn, TCMPBn. And then, set TCNTBn, TCMPBn as 80(40+40), 40 to determine the next reload value.
2. Start Timer by setting the start bit and manual updata bit off.
3. When TCNTn has the same value with TCMPn, the logic level of TOUTn is changed from low to high
4. When TCNTn reaches to 0, TCNTn is reloaded automatically with TCNTBn. At the same time, the interrupt
request is generated.
5. In the ISR (interrupt service routine), the TCNTBn and TCMPBn is set as 80(20+60) and 60, which is used for
next duration.
6. When TCNTn has the same value with TCMPn, the logic level of TOUTn is changed from low to high
7. When TCNTn reaches to 0, TCNTn is reloaded automatically with TCNTBn. At the same time, the interrupt
request is generated.
8. In the ISR (interrupt service routine), auto-reload and interrupt request are disabled to stop the timer.
9. When TCNTn has the same value with TCMPn, the logic level of TOUTn is changed from low to high
10. Even when TCNTn reaches to 0, TCNTn is not any more reloaded and the timer is stopped because
auto-reload is disabled.

determined by TCMPBn in the Figure 19-8.
For higher PWM value, decrease TCMPBn value. For lower PWM value, increase TCMPBn value. If output
inverter is enabled, the increment/decrement may be opposite.
Because of double buffering feature, TCMPBn, for a next PWM cycle, can be written in any point of current PWM

The following methods can be used to maintain TOUT as high or low. (Assume the inverter is off)
Turn off the auto-reload bit. And then, TOUTn goes to high level and the timer is stopped after TCNTn reaches to
0. This method is recommended.
Stop the timer by clearing the timer start/stop bit to 0. If TCNTn <= TCMPn, the ouput level is high. If TCNTn

cn / louishan at 2015.01.13
The dead zone is for the PWM control of power devices. This feature is used to insert the time gap between a
turn-off of a switching device and a turn on of the other switching device. This time gap prohibit the two switching
device turning on simultaneously even for a very short time.
TOUT0 is the PWM output. nTOUT0 is the inversion of the TOUT0. If the dead-zone is enabled, the output waveform of TOUT0,nTOUT0 will be TOUT0_DZ and nTOUT0_DZ. TOUT0_DZ and nTOUT0_DZ never can be turned
on simultaneously by the dead zone interval. For functional correctness, the dead zone length must be set smaller
than compare counter value.
19.4.7 Timer Interrupt Generation
The PWMTIMER provides flexibility to generate Pulse and Level Interrupts by controlling the "INTRGEN_SEL"
port status. When the port "INTRGEN_SEL" is tied to logic 1, optional level interrupts will be, generated else
optional pulse interrupts will be generated. The interrupt generation is controlled by writing specific values to the
"TINT_CSTAT" register within PWMTIMER. Also, interrupt generations is optional based on programmed value in
"TINT_CSTAT'' register.

S5P4418_UM
20 Analog Digital Converter (ADC)
20.4 Functional Description
The S5P4418 can receive eight ADC inputs and select one of the ADC inputs by using ADCCON.ASEL[2:0]. The
sizes of the eight ADC inputs depend on the size of VREF.
The ADC controller uses PCLK and the PCLK is divided in the Prescaler and applied to the ADC. At this time, the
ADCCON.APEN bit is used for the application of CLKIN. Clock divide values by the Prescaler are available from
20 to 256. (Actually, since the register input value is [Clock Divide Value - 1], smaller divide values make the
sampling more detailed. The clock divide value is determined by *ADCCON.APSV*bit.
If the ADC block continuously accepts after power is applied, it consumes current unnecessarily. In this case, it is
better to power down the A/D converter by using the ADCCON.STBY bit. The ADCCON.STBY bit determines the
power input for the ADC block. If the ADCCON.STBY bit is "0", the ADC block waits for ADC input after power on.
After that, if the ADCCON.ADEN bit is set as "1" to accept ADC input, the ADC operation is actually performed.
On the other hand, if the ADCCON.STBY bit is "1", the ADC block goes to power down status, that is, power is not
applied. This is called Standby mode. (In Standby mode, only about 20 uA current is consumed.
If the ADC block is not used, set the ADCCON.STBY bit as "1" and power off the ADC block. In this way,
unnecessary power consumption by the ADC block can be reduced. In addition, since the supply of the clock can
be determined by using the ADCCON.APEN bit, power consumption can be reduced further by stopping the clock
supply when supply is unnecessary.

Main Waveform
Figure 20-2 shows the timing chart for the ADC. AIN[7:0] is continuously input from the outside and CLKIN is
supplied via the ADCCON.APEN bit. After AIN[7:0] is selected, by using ASEL[2:0], the ADCCON.STBY bit is set
as "0" to supply power to the ADC block. Finally, A/D conversion is progressed by setting the ADCCON.ADEN bit
as "1".After the conversion is completed, EDO occurs and the ADCCON.ADEN bit is automatically cleared to "0".
After that, A/D Converted Data (D1) can be read through ADCDAT.ADCDAT. Since it always takes 5-cycles for
10-bit conversion, the maximum conversion rate of the S5P4418 is 1MSPS.Set the ADCCON.ADEN bit as "1" to
operate the ADC again.

21 I2C Controller
I2C Controller
21.1 Overview
The S5P4418 application processor can support a multi-master I2C-bus serial interface. A dedicated serial data
line (SDA) and a serial clock line (SCL) carry information between bus masters and peripheral devices which are
connected to the I2C-bus. The SDA and SCL lines are bi-directional. Devices communicating with each other on a
serial bus must have some form of protocol that avoids all possibilities of confusion, data loss and blockage of
information. The system must not be dependent on the devices connected to it, otherwise modifications or
improvements would be impossible.
In multi-master I2C-bus mode, multiple microprocessor can receive or transmit serial data to or from slave
devices. The master that initiates a data transfer over the I2C-bus is responsible for terminating the transfer.
21.2 Features
Compliance to the AMBA specification onwards for easy integration into SoC implementation
Only 2 bus lines are required; a serial data line (SDA) and a serial clock line (SCL). The simple 2-wire serial
I2C-bus minimizes interconnections so ICs have fewer pins.
The completely integrated I2C-bus protocol eliminates the need for address decoders and other glue logic.
Each device connected to the bus is software addressable by a unique address and simple master/slave
relationships exist at all times; master can operate as master-transmitter or as master-receiver.
It is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or
more masters simultaneously initiate data transfer.
Serial, 8-bit oriented, bi-directional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to
400 kbit/s in the Fast-mode
The number of ICs that can be connected to the same bus is limited only by a maximum bus capacitance of
400 pF.
System bus asynchronous reset is not supported.
Every operation command used in I2C-bus needs delays of minimum 3 Cycles (PCLK) between them.
High speed mode, combined format, 10-bit address are not supported

21.3 Functional Description
21.3.1 The Concept of the I2C-Bus
The I2C-bus interface has four operation modes:
Master transmitter mode
Master receiver mode
Slave transmitter mode
Slave receiver mode
Two wires, serial data (SDA) and serial clock (SCL), carry information between the devices connected to the bus.
Each device is recognized by a unique address (whether it's a microcontroller, LCD driver, memory or keyboard
interface) and operate as either a transmitter or receiver, depending on the function of the device. In addition to
transmitters and receivers, devices can also be considered as masters or slaves when performing data transfer. A
master is the device which initiates a data transfer on the bus and generates the clock signals to permit that
transfer. At that time, any device addressed is considered a slave. Table 21-1 shows the basic terminology of I2Cbus.

21.3.2 IC Protocol
Both SDA and SCL are bi-directional lines, connected to a positive supply voltage via a current-source or pull-up
resistor. Figure 21-1 shows the hardware layout of the I2C-bus. When the bus is free, both lines are HIGH. The
output stages of devices connected to the bus must have an open-drain or open-collector to perform the wiredAND function. Data on the I2C-bus can be transferred at rates of up to 100 kbit/s in the Standard-mode or up to
400 kbit/s in the Fast-mode.
Figure 21-2 shows additional information of I2C-bus pad structure.

21.3.3 Start/Stop Operation
Within the procedure of the I2C-bus, unique situations arise which are defined as START (S) and STOP (P)
condition. A HIGH to LOW transition on the SDA line while SCL is HIGH is one such unique case. This situation
indicates a START condition. A LOW to HIGH transition on the SDA line while SCL is HIGH defines a STOP
condition.
START and STOP condition are always generated by the master. The bus is considered to be busy after the
START condition. The bus is considered to be free again a certain time after the STOP condition.

21.3.4 Data Format
The first seven bits of the first byte make up the slave address. The eighth bit is the LSB (Least Significant Bit). It
determines the direction of the message. A zero in the least significant position of the first byte means that the
master will write information to a selected slave. A one in this position means that the master will read information
from the slave. A data transfer is always terminated by a STOP condition (P) generated by the master. The first
acknowledge is generated by the slave. But the acknowledge of data is generated by the receiver. Figure 21-4
shows the 7-bit data format.
Possible data transfer formats are:
Master-transfer transmits to slave receiver.
Master reads slave immediately after first byte. At the moment of the first acknowledge, the master-transfer
becomes a master-receiver and the slave-receiver becomes a slave-transfer.
Combined format is not supported.
NOTE: A START condition immediately followed by a STOP condition (void message) is an illegal format.

21.3.5 Data Transfer
Every byte put on the SDA line must be eight bits long. The number of bytes which can be transmitted per transfer
is unrestricted. The address byte is transmitted by the master when the I2C-bus is operating in master mode.
When a master initiates a start condition, it sends its slave address onto the bus. The address byte consists of a
7-bit address and a 1-bit transfer direction indicator (that is, write or read). If bit 8 is "0", a transmit operation
(write) is indicated; if bit 8 is "1", a request for data (read) is indicated.
The master ends the indicated transfer operation by transmitting a stop condition. If the master wants to continue
sending data over the bus, it can generate another start condition and another slave address. Each byte must be
followed by an acknowledge (ACK) bit. Serial data and addresses are transferred with the most significant bit
(MSB) first. In this way, read-write operations can be performed in various formats. Figure 21-5 shows the
sequence of data transmission.

21.3.6 Arbitration
Arbitration takes place on the SDA line to prevent contention on the bus between two masters, while the SCL line
is at the HIGH level. If a master with a SDA High level detects another master with a SDA Low level, it will not
initiate a data transfer because the current level on the bus dose not correspond to its own. The master that loses
the arbitration can generate clock pulses until the end of the last-transmitted data byte. The arbitration procedure
can continue while data continues to be transferred over the bus. Figure 21-6 shows the arbitration.
The first stage of arbitration is the comparison of address bits. If a master loses the arbitration during the
addressing stage of a data transfer, it is possible that the master which won the arbitration is attempting to
address the master which lost. In this case, the losing master must immediately switch to the slave receiver mode.

21.3.7 Synchronization
Clock synchronization is performed using the wired-AND connection of I2C-bus interface to the SCL line. This
means that a HIGH to LOW transition on the SCL line will cause the devices concerned to start counting off their
LOW period and, once a device clock has gone LOW, it will hold SCL line in that state until the clock HIGH state is
reached. However, the LOW to HIGH transition of this clock may not change the state of the SCL line if another
clock is still within its LOW period. In this way, a synchronized SCL clock is generated with its LOW period
determined by the device with the longest clock LOW period and its HIGH period determined by the one with the
shortest clock HIGH period. Devices with shorter LOW periods enter a HIGH wait-state during this time. Figure
21-7 shows the procedure of SCL generation.

21.3.8 Acknowledge
Data transfer with acknowledge is obligatory. To complete one-byte transfer operation, the receiver must send an
ACK bit to the transmitter. The ACK pulse occurs at the ninth clock of the SCL line (eight clocks are required to
complete the one-byte transfer).
The transmitter releases the SDA line (that is, it sends the SDA line High) when the ACK clock pulse is received.
The receiver must drive the SDA line Low during the ACK clock pulse so that SDA is Low during the High period
of the ninth SCL pulse.
The ACK bit transmit function can be enable and disabled by software (ICCR[7]). Figure 21-8 shows data transfer
with acknowledge signal.

21.3.9 Read/Write Operation
When operating in transmitter mode, the I2C-bus interface interrupt routine waits for the master to write a data
byte into the I2C-bus data shift register (IDSR). To do this, it holds the SCL line Low prior to transmission. In
receive mode, the I2C-bus interface waits for the master to read the byte from the I2C-bus data shift register
(IDSR). It does this by holding the SCL line Low following the complete reception of a data byte.
21.3.10 Configuration I2C-Bus
Data transfer with acknowledge is obligatory. To complete one-byte transfer operation, the receiver must send an
ACK bit to the transmitter. The ACK to control the frequency of the serial clock (SCL), user has to program the 4bit prescaler value in the ICCR register.

22 SPI/SSP
22.4 Functional Description
22.4.1 Clock Generation Configuration
SPI/SSP operates by using the PCLK and the SSPCLK. The PCLK is used when the CPU accesses the registers
of the SPI/SSP. And, users can adjust the PCLK for the SPI/SSP by setting the PCLKMODE parameters
according to their purpose. The PCLK is generated by Clock Generator of the SPI/SSP.
The SSPCLK is used when the SPI/SSP transmit or receive SPI/SSP Protocol. SSPCLK is generated by Clock
Generator of the SPI/SSP. Each SPI/SSP has own Clock Generator. Therefore, users must set up the SPI/SSP
Clock Generator before the SPI configuration stage.
22.4.2 Clock Ratios
There is a constraint on the ratio of the frequencies of PCLK to SSPCLK. The frequency of SSPCLK must be less
than or equal to that of PCLK. This ensures that control signals from the SSPCLK domain to the PCLK domain are
certain to get synchronized before one frame duration:
FSSPCLK<= FPCLK.(FSSPCLK<=100 MHz)
In the slave mode of operation, the SSPCLKIN signal from the external master is double synchronized and then
delayed to detect an edge. It takes three SSPCLKs to detect an edge on SSPCLKIN. SSPTXD has less setup
time to the falling edge of SSPCLKIN on which the master is sampling the line. The setup and hold times on
SSPRXD with reference to SSPCLKIN must be more conservative to ensure that it is at the right value when the
actual sampling occurs within the SSPMS. To ensure correct device operation, SSPCLK must be at least 12 times
faster than the maximum expected frequency of SSPCLKIN.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The frequency selected for SSPCLK must accommodate the desired range of bit clock rates. The ratio of
minimum SSPCLK frequency to SSPCLKOUT maximum frequency in the case of the slave mode is 12 and for the
master mode it is two.
To generate a maximum bit rate of 1.8432 Mbps in the Master mode, the frequency of SSPCLK must be at least
3.6864 MHz. With an SSPCLK frequency of 3.6864 MHz, the SSPCPSR register has to be programmed with a
value of two and the SCR[7:0] field in the SSPCR0 register needs to be programmed as zero.
To work with a maximum bit rate of 1.8432 Mbps in the slave mode, the frequency of SSPCLK must be at least
22.12 MHz. With an SSPCLK frequency of 22.12 MHz, the SSPCPSR register can be programmed with a value of
12 and the SCR[7:0] field in the SSPCR0 register can be programmed as zero. Similarly the ratio of SSPCLK
maximum frequency to SSPCLKOUT minimum frequency is 254 256.
The minimum frequency of SSPCLK is governed by the following equations, both of which have to be satisfied:
FSSPCLK(Min.) => 2 FSSPCLKOUT(Max.) [for master mode]
FSSPCLK(Min.) => 12 FSSPCLKIN(Max.) [for slave mode].
The maximum frequency of SSPCLK is governed by the following equations, both of which have to be satisfied:
FSSPCLK(Max.) <= 254 256 FSSPCLKOUT(Min.) [for master mode]
FSSPCLK(Max.) <= 254 256 FSSPCLKIN(Min.) [for slave mode]

Program the serial clock rate
Select one of the three protocols
Select the data word size (where applicable)
SSPCPSR register is used to
Program the serial clock prescale divisor
The serial bit rate is derived by dividing down the input clock SSPCLK. The clock is first divided by an even
prescale value CPSDVSR from 2 to 254, which is programmed in SSPCPSR. The clock is further divided by a
value from 1 to 256, which is 1 + SCR, where SCR is the value programmed in SSPCR0.
The frequency of the output signal bit clock SSPCLKOUT is defined below:

22.4.3 Operation
The SPI/SSP Block transfers Serial Data from/to External device via FIFO in the SPI/SSP Block. The transfer
operation is initiated by CPU, using the programmed I/O system or the DMA, to/from the system memory. The
SPI/SSP Data transfer is performed in full duplex.
When the SPI/SSP sends Data to the PIO mode, the transfer operation is completed by Reading "Read FIFO" or
Writing to "Write FIFO" by means of a program.
In the case of communication with DMA mode, For DMA transfer mode, user must set up the DMA configuration
and set as "1" 'the SSPDMACR.TXDMAE bit and the SSPDMACR.RXDMAE bit in the SPI/SSP to enable the
DMA transfer Request from SPI/SSP. RX Request occurs when Receive FIFO has 4 more than data, TX Request
occurs when Transmit FIFO has 4 less than data. User can't adjust this configuration.
22.4.3.1 Transmit and Receive Operation
When configured as a master, the clock to the attached slaves is derived from a divided down version of SSPCLK
through the prescaler operations described previously. The master transmit logic successively reads a value from
its transmit FIFO and performs
Parallel to serial conversion on it. Then the serial data stream and frame control signal, synchronized to
SSPCLKOUT, are output through the SSPTXD pin to the attached slaves. The master receive logic performs
serial to parallel conversion on the incoming
SAMSUNG

cn / louishan at 2015.01.13
Synchronous SSPRXD data stream, extracting and storing values into its receive FIFO, for subsequent reading
through the APB interface.
NOTE: SSPRXD data is only valid when FSSPCLKOUT (Frequency of SSPCLKOUT) is lower than 20 MHz. This Constraint
may be changed by exterior device's specification.
When configured as a slave, the SSPCLKIN clock is provided by an attached master and used to time its
transmission and reception sequences. The slave transmit logic, under control of the master clock, successively
reads a value from its transmit FIFO, performs parallel to serial conversion, then output the serial data stream and
frame control signal through the slave SSPTXD pin. The slave receive logic performs serial to parallel conversion
on the incoming SSPRXD data stream, extracting and storing values into its receive FIFO, for subsequent reading
through the APB interface.

22 SPI/SSP
22.4.3.2 Reset Operation
The SPI/SSP is reset by the global reset signal PRESETn and a block-specific reset signal nSSPRST. An external
reset controller must use PRESETn to assert nSSPRST asynchronously and negate it synchronously to SSPCLK.
PRESETn must be asserted LOW for a period long enough to reset the slowest block in the on-chip system, and
then taken HIGH again. The SPI/SSP requires PRESETn to be asserted LOW for at least one period of PCLK.
In S5P4418, PRESETn and nSSPRST is controlled by Reset Controller. User can set up SPI/SSP reset signals by
CPU.
22.4.3.3 Interrupts
There are 4 maskable interrupts generated in the SPI/SSP. These are combined to produce one interrupt outputs.

22.4.4 Frame Format
Each data frame is between 4 and 16 bits long depending on the size of data programmed, and is transmitted
starting with the MSB. There are three basic frame types that can be selected:
Texas Instruments synchronous serial
Motorola SPI
National Semiconductor Microwire.
For all three formats, the serial clock (SSPCLKOUT) is held inactive while the SPI/SSP is idle, and transitions at
the programmed frequency only during active transmission or reception of data. The idle state of SSPCLKOUT is
utilized to provide a receive timeout indication that occurs when the receive FIFO still contains data after a timeout
period.
For Motorola SPI and National Semiconductor Microwire frame formats, the serial frame (SSPFSSOUT) pin is
active LOW, and is asserted (pulled down) during the entire transmission of the frame.
For Texas Instruments synchronous serial frame format, the SSPFSSOUT pin is pulsed for one serial clock period
starting at its rising edge, prior to the transmission of each frame. For this frame format, both the SPI/SSP and the
off-chip slave device drive their output data on the rising edge of SSPCLKOUT, and latch data from the other
device on the falling edge.
Unlike the full-duplex transmission of the other two frame formats, the National Semiconductor Microwire format
uses a special master-slave messaging technique, which operates at half-duplex. In this mode, when a frame
begins, an 8-bit control message is transmitted to the off-chip slave. During this transmit, no incoming data is
received by the SSP. After the message has been sent, the off-chip slave decodes it and, after waiting one serial
clock after the last bit of the 8-bit control message has been sent, responds with the requested data. The returned
data can be 4 to 16 bits in length, making the total frame length anywhere from 13 to 25 bits.

In this mode, SSPCLKOUT and SSPFSSOUT are forced LOW, and the transmit data line SSPTXD is tri-stated
whenever the SPI/SSP is idle. Once the bottom entry of the transmit FIFO contains data, SSPFSSOUT is pulsed
HIGH for one SSPCLKOUT period. The value to be transmitted is also transferred from the transmit FIFO to the
serial shift register of the transmit logic. On the next rising edge of SSPCLKOUT, the MSB of the 4 to 16-bit data
frame is shifted out on the SSPTXD pin. Likewise, the MSB of the received data is shifted onto the SSPRXD pin
by the off-chip serial slave device.
Both the SPI/SSP and the off-chip serial slave device then clock each data bit into their serial shifter on the falling
edge of each SSPCLKOUT. The received data is transferred from the serial shifter to the receive FIFO on the first
rising edge of SSPCLKOUT after the LSB has been latched.

22.4.4.2 Motorola SPI Frame Format
The Motorola SPI interface is a four-wire interface where the SSPFSSOUT signal behaves as a slave select. The
main feature of the Motorola SPI format is that the inactive state and phase of the SSPCLKOUT signal are
programmable through the SPO and SPH bits within the SSPSCR0 control register.
SPO, clock polarity
When the SPO clock polarity control bit is LOW, it produces a steady state low value on the SSPCLKOUT pin. If
the SPO clock polarity control bit is HIGH, a steady state high value is placed on the SSPCLKOUT pin when data
is not being transferred.
SPH, clock phase
The SPH control bit selects the clock edge that captures data and allows it to change state. It has the most impact
on the first bit transmitted by either allowing or not allowing a clock transition before the first data capture edge.
When the SPH phase control bit is LOW, data is captured on the first clock edge transition. If the SPH clock phase
control bit is HIGH, data is captured on the second clock edge transition.

In this configuration, during idle periods:
The SSPCLKOUT signal is forced LOW
SSPFSSOUT is forced HIGH
The transmit data line SSPTXD is arbitrarily forced LOW
If the SPI/SSP is enabled and there is valid data within the transmit FIFO, the start of transmission is signified by
the SSPFSSOUT master signal being driven LOW. This causes slave data to be enabled onto the SSPRXD input
line of the master. The nSSPOE line is driven LOW, enabling the master SSPTXD output pad.
One half SSPCLKOUT period later, valid master data is transferred to the SSPTXD pin. Now that both the master
and slave data have been set, the SSPCLKOUT master clock pin goes HIGH after one further half SSPCLKOUT
period.
The data is now captured on the rising and propagated on the falling edges of the SSPCLKOUT signal.
In the case of a single word transmission, after all bits of the data word have been transferred, the SSPFSSOUT
line is returned to its idle HIGH state one SSPCLKOUT period after the last bit has been captured.
However, in the case of continuous back-to-back transmissions, the SSPFSSOUT signal must be pulsed HIGH
between each data word transfer. This is because the slave select pin freezes the data in its serial peripheral
register and does not allow it to be altered if the SPH bit is logic zero. Therefore the master device must raise the
SSPFSSIN pin of the slave device between each data transfer to enable the serial peripheral data write. On
completion of the continuous transfer, the SSPFSSOUT pin is returned to its idle state one SSPCLKOUT period
after the last bit has been captured.

However, in the case of continuous back-to-back transmissions, the SSPFSSOUT signal must be pulsed HIGH
between each data word transfer. This is because the slave select pin freezes the data in its serial peripheral
register and does not allow it to be altered if the SPH bit is logic zero. Therefore the master device must raise the
SSPFSSIN pin of the slave device between each data transfer to enable the serial peripheral data write. On
completion of the continuous transfer, the SSPFSSOUT pin is returned to its idle state one SSPCLKOUT period
after the last bit has been captured.

SAMSUNG

cn / louishan at 2015.01.13
If the SPI/SSP is enabled and there is valid data within the transmit FIFO, the start of transmission is signified by
the SSPFSSOUT master signal being driven LOW. The nSSPOE line is driven LOW, enabling the master
SSPTXD output pad. After a further one half SSPCLKOUT period, both master and slave data are enabled onto
their respective transmission lines. At the same time, the SSPCLKOUT is enabled with a falling edge transition.
Data is then captured on the rising edges and propagated on the falling edges of the SSPCLKOUT signal.
After all bits have been transferred, in the case of a single word transmission, the SSPFSSOUT line is returned to
its idle HIGH state one SSPCLKOUT period after the last bit has been captured.
For continuous back-to-back transmissions, the SSPFSSOUT pins remains in its active LOW state, until the final
bit of the last word has been captured, and then returns to its idle state as described above.
For continuous back-to-back transfers, the SSPFSSOUT pin is held LOW between successive data words and
termination is the same as that of the single word transfer.

22.4.4.7 National Semiconductor Microwire Frame Format
Figure 22-10 shows the National Semiconductor Microwire frame format, again for a single frame. Figure 22-11
shows the same format when back to back frames are transmitted.
Figure 22-10
Microwire frame format (single transfer)
Microwire format is very similar to SPI format, except that transmission is half-duplex instead of full-duplex, using
a master-slave message passing technique. Each serial transmission begins with an 8-bit control word that is
transmitted from the SPI/SSP to the off-chip slave device. During this transmission, no incoming data is received
by the SPI/SSP. After the message has been sent, the off-chip slave decodes it and, after waiting one serial clock
after the last bit of the 8-bit control message has been sent, responds with the required data. The returned data is
4 to 16 bits in length, making the total frame length anywhere from 13 to 25 bits.

In this configuration, during idle periods:
The SSPCLKOUT signal is forced LOW
SSPFSSOUT is forced HIGH
The transmit data line SSPTXD is arbitrarily forced LOW
A transmission is triggered by writing a control byte to the transmit FIFO. The falling edge of SSPFSSOUT causes
the value contained in the bottom entry of the transmit FIFO to be transferred to the serial shift register of the
transmit logic, and the MSB of the 8-bit control frame to be shifted out onto the SSPTXD pin. SSPFSSOUT
remains LOW for the duration of the frame transmission. The SSPRXD pin remains tri-stated during this
transmission.
The off-chip serial slave device latches each control bit into its serial shifter on the rising edge of each
SSPCLKOUT. After the last bit is latched by the slave device, the control byte is decoded during a one clock waitstate, and the slave responds by transmitting data back to the SPI/SSP. Each bit is driven onto SSPRXD line on
the falling edge of SSPCLKOUT. The SPI/SSP in turn latches each bit on the rising edge of SSPCLKOUT. At the
end of the frame, for single transfers, the SSPFSSOUT signal is pulled HIGH one clock period after the last bit has
been latched in the receive serial shifter, that causes the data to be transferred to the receive FIFO.
NOTE: The off-chip slave device can tri-state the receive line either on the falling edge of SSPCLKOUT after the LSB has
been latched by the receive shifter, or when the SSPFSSOUT pin goes HIGH.

For continuous transfers, data transmission begins and ends in the same manner as a single transfer. However,
the SSPFSSOUT line is continuously asserted (held LOW) and transmission of data occurs back to back. The
control byte of the next frame follows directly after the LSB of the received data from the current frame. Each of
the received values is transferred from the receive shifter on the falling edge SSPCLKOUT, after the LSB of the
frame has been latched into the SPI/SSP.

Setup and hold time requirements on SSPFSSIN with respect to SSPCLKIN in Microwire mode
In the Microwire mode, the SPI/SSP slave samples the first bit of receive data on the rising edge of SSPCLKIN
after SSPFSSIN has gone LOW. Masters that drive a free-running SSPCKLIN must ensure that the SSPFSSIN
signal has sufficient setup and hold margins with respect to the rising edge of SSPCLKIN.
SAMSUNG

cn / louishan at 2015.01.13
Figure 22-12 illustrates these setup and hold time requirements. With respect to the SSPCLKIN rising edge on
which the first bit of receive data is to be sampled by the SPI/SSP slave, SSPFSSIN must have a setup of at least
two times the period of SSPCLKIN on which the SPI/SSP operates. With respect to the SSPCLKIN rising edge
previous to this edge, SSPFSSIN must have a hold of at least one SSPCLKIN period.

External devices can provide clocks as well as MPEG TS timing. Figure 23-2 shows the types of clock that can be
provided by external devices. The clock types are determined by the point at which the external devices output
data.
A type devices output data on the rising edge. The value of the CAP_CTRL.CAP_CLK_POL bit is "0", and the
MPEG TSP reads data on the point of the falling edge as above described.
B type devices output data on the falling edge. The value of the CAP_CTRL.CAP_CLK_POL bit is "1".
C type Devices very similar to the A type device are used. The point of difference from an A type device is that
these devices do not check Parity.
D type Devices very similar to the B type device are used. The point of difference from a B type device is that
these devices do not check Parity.
If the value of TSI_DP is "1", the value indicates Data. If the value is "0", the value indicates Parity. However, the
value may have the opposite meaning depending on device properties. In this case, its polarity can be changed by
setting the MPEGIFCONT.DP_POL bit as "1".

UART_ISO7816
24.1 Overview
The UART performs:
Serial-to-parallel conversion on data received from a peripheral device
Parallel-to-serial conversion on data transmitted to the peripheral device.
The CPU reads and writes data and control/status information through the AMBA APB interface. The transmit and
receive paths are buffered with internal FIFO memories enabling up to 32 bytes to be stored independently in both
transmit and receive modes.
The UART:
Includes a programmable baud rate generator that generates a common transmit and receive internal clock
from the UART internal reference clock input, UARTCLK
Offers similar functionality to the industry-standard 16C650 UART device
Supports the following maximum baud rates:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
921600 bps, in UART mode
460800 bps, in IrDA mode
115200 bps, in low-power IrDA mode.
The UART operation and baud rate values are controlled by the Line Control Register, UARTLCR_H and the baud
rate divisor registers (Integer Baud Rate Register, UARTIBRD and Fractional Baud Rate Register, UARTFBRD.
The UART can generate:
Individually-maskable interrupts from the receive (including timeout), transmit, modem status and error
conditions
A single combined interrupt so that the output is asserted if any of the individual interrupts are asserted, and
unmasked
DMA request signals for interfacing with a Direct Memory Access (DMA) controller.
If a framing, parity, or break error occurs during reception, the appropriate error bit is set, and is stored in the
FIFO. If an overrun condition occurs, the overrun register bit is set immediately and FIFO data is prevented from
being overwritten.
You can program the FIFOs to be 1 byte deep providing a conventional double-buffered UART interface.
The modem status input signals Clear to Send (CTS), Data Carrier Detect (DCD), Data Set Ready (DSR), and
Ring Indicator (RI) are supported. The output modem control lines, Request to Send (RTS), and Data Terminal
Ready (DTR) are also supported.

24 UART_ISO7816
There is a programmable hardware flow control feature that uses the nUARTCTS input and the nUARTRTS
output to automatically control the serial data flow.
The device is a cyclic type monolithic ADC, which provides an on-chip sample-and-hold and power down mode.
IrDA SIR block
The IrDA Serial Infra-Red (SIR) block contains an IrDA SIR protocol ENDEC. The SIR protocol ENDEC can be
enabled for serial communication through signals nSIROUT and SIRIN to an infrared transducer instead of using
the UART signals UARTTXD and UARTRXD.
If the SIR protocol ENDEC is enabled, the UARTTXD line is held in the passive state (HIGH) and transitions of the
modem status, or the UARTRXD line have no effect. The SIR protocol ENDEC can receive and transmit, but it is
half-duplex only, so it cannot receive while transmitting, or transmit while receiving.
The IrDA SIR physical layer specifies a minimum 10 ms delay between transmission and reception.

24.2 Features
The UART provides:
Compliance to the AMBA Specification (Rev 2.0) onwards for easy integration into SoC implementation.
Programmable use of UART or IrDA SIR input/output.
Separate 32 8 transmit and 32 12 receive First-In, First-Out (FIFO) memory buffers to reduce CPU
interrupts.
Programmable FIFO disabling for 1 byte depth.
Programmable baud rate generator. This enables division of the reference clock by (1 16) to (65535 16)
and generates an internal 16 clock. The divisor can be a fractional number enabling you to use any clock
with a frequency > 3.6864 MHz as the reference clock.
Standard asynchronous communication bits (start, stop and parity). These are added prior to transmission
and removed on reception.
Independent masking of transmit FIFO, receive FIFO, receive timeout, modem status, and error condition
interrupts.
Support for Direct Memory Access (DMA): UART0, UART1, and UART2 only
False start bit detection.
Line break generation and detection.
Support of the modem control functions CTS, DCD, DSR, RTS, DTR, and RI: UART1 only
Programmable hardware flow control.
Fully-programmable serial interface characteristics:

AMBA APB interface
The AMBA APB interface generates read and write decodes for accesses to status/control registers, and the
transmit and receive FIFOs.
Register block
The register block stores data written, or to be read across the AMBA APB interface.
Baud rate generator
The baud rate generator contains free-running counters that generate the internal 16 clocks, Baud16 and
IrLPBaud16 signals. Baud16 provides timing information for UART transmit and receive control. Baud16 is a
stream of pulses with a width of one UARTCLK clock period and a frequency of 16 times the baud rate.
IrLPBaud16provides timing information to generate the pulse width of the IrDA encoded transmit bit stream when
in low-power IrDA mode.
Transmit FIFO
The transmit FIFO is an 8-bit wide, 32 location deep, FIFO memory buffer. CPU data written across the APB
interface is stored in the FIFO until read out by the transmit logic. You can disable the transmit FIFO to act like a
one-byte holding register. The receive logic performs serial-to-parallel conversion on the received bit stream after
a valid start pulse has been detected. Overrun, parity, frame error checking, and line break detection are also
performed, and their status accompanies the data that is written to the receive FIFO.

Receive FIFO
The receive FIFO is a 12-bit wide, 32 location deep, FIFO memory buffer. Received data and corresponding error
bits, are stored in the receive FIFO by the receive logic until read out by the CPU across the APB interface. The
receive FIFO can be disabled to act like a one-byte holding register.
Transmit logic
The transmit logic performs parallel-to-serial conversion on the data read from the transmit FIFO. Control logic
outputs the serial bit stream beginning with a start bit, data bits with the Least Significant Bit (LSB) first, followed
by the parity bit, and then the stop bits according to the programmed configuration in control registers.
Receive logic
The receive logic performs serial-to-parallel conversion on the received bit stream after a valid start pulse has
been detected. Overrun, parity, frame error checking, and line break detection are also performed, and their status
accompanies the data that is written to the receive FIFO.

Interrupt generation logic
Individual mask-able active HIGH interrupts are generated by the UART. A combined interrupt output is also
generated as an OR function of the individual interrupt requests. You can use the single combined interrupt with a
system interrupt controller that provides another level of masking on a per-peripheral basis. This enables you to
use modular device drivers that always know where to find the interrupt source control register bits.
You can also use the individual interrupt requests with a system interrupt controller that provides masking for the
outputs of each peripheral. In this way, a global interrupt service routine can read the entire set of sources from
one wide register in the system interrupt controller. This is attractive where the time to read from the peripheral
registers is significant compared to the CPU clock speed in a real-time system.
DMA interface
The UART provides an interface to connect to the DMA controller.
Synchronizing registers and logic
The UART supports both asynchronous and synchronous operation of the clocks, PCLK and UARTCLK.
Synchronization registers and handshaking logic have been implemented, and are active at all times. This has a
minimal impact on performance or area. Synchronization of control signals is performed on both directions of data
flow, that is from the PCLK to the UARTCLK domain, and from the UARTCLK to the PCLK domain.

Figure 24-2
IrDA SIR RNDEC Block Diagram
24.3.1.1 IrDA SIR Transmit Encoder
The SIR transmit encoder modulates the Non Return-to-Zero (NRZ) transmit bit stream output from the UART.
The IrDA SIR physical layer specifies use of a Return to Zero, Inverted (RZI) modulation scheme that represents
logic 0 as an infrared light pulse. The modulated output pulse stream is transmitted to an external output driver
and infrared Light Emitting Diode (LED).
In IrDA mode the transmitted pulse width is specified as three times the period of the internal 16 clock (Baud16),
that is, 3/16 of a bit period.
In low-power IrDA mode the transmit pulse width is specified as 3/16 of a 115200 bps bit period. This is
implemented as three times the period of a nominal 1.8432 MHz clock (IrLPBaud16) derived from dividing down of
UARTCLK clock. The frequency ofIrLPBaud16 is set up by writing the appropriate divisor value to the IrDA LowPower Counter Register, UARTILPR.
The active low encoder output is normally LOW for the marking state (no light pulse).The encoder outputs a high
pulse to generate an infrared light pulse representing a logic 0 or spacing state.
In normal and low-power IrDA modes, when the fractional baud rate divider is used, the transmitted SIR pulse
stream includes an increased amount of jitter. This jitter is because the Baud16 pulses cannot be generated at
regular intervals when fractional division is used. That is, the Baud16 cycles have a different number of UARTCLK
cycles. It can be shown that the worst case jitter in the SIR pulse stream can be up to three UARTCLK cycles.
This is within the limits of the SIR IrDA Specification where the maximum amount of jitter permitted is 13 %,
provided the UARTCLK is > 3.6864 MHz and the maximum baud rate used for IrDA mode is 115200 bps. With
these conditions, the jitter is less than 9 %.

24.3.1.2 IrDA SIR Receive Decoder
The SIR receive decoder demodulates the return-to-zero bit stream from the infrared detector and outputs the
received NRZ serial bit stream to the UART received data input. The decoder input is normally HIGH (marking
state) in the idle state. The transmit encoder output has the opposite polarity to the decoder input.
A start bit is detected when the decoder input is LOW.
NOTE: To prevent the UART from responding to glitches on the received data input then it ignores SIRIN pulses that are less
than:
3/16 of Baud16, in IrDA mode
3/16 of IrLPBaud16, in low-power IrDA mode.

24.4 Operation
24.4.1 Interface Reset
The UART and IrDA SIR ENDEC are reset by the global reset signal PRESETn and a block-specific reset signal
nUARTRST. An external reset controller must use PRESETn to assert nUARTRST asynchronously and negate it
synchronously to UARTCLK. PRESETn must be asserted LOW for a period long enough to reset the slowest
block in the on-chip system, and then be taken HIGH again. The UART requires PRESETn to be asserted LOW
for at least one period of PCLK.
24.4.2 Clock Signals
The frequency selected for UARTCLK must accommodate the required range of baud rates:
FUARTCLK (Min.) 16 baud-rate (Max.)
FUARTCLK (Max.) 16 65535 baud-rate (Min.)
For example, for a range of baud rates from 110 baud to 460800 baud the UARTCLK frequency must be between
7.3728 MHz to 115.34 MHz.
The frequency of UARTCLK must also be within the required error limits for all baud rates to be used.
There is also a constraint on the ratio of clock frequencies for PCLK to UARTCLK. The frequency of UARTCLK
must be no more than 5/3 times faster than the frequency of PCLK:

For example, in UART mode, to generate 921600 baud when UARTCLK is14.7456 MHz then PCLK must be
greater than or equal to 8.85276 MHz. This ensures that the UART has sufficient time to write the received data to
the receive FIFO.

24.4.3 UART Operation
Control data is written to the UART Line Control Register, UARTLCR. This register is 30 bits wide internally, but is
externally accessed through the APB interface by writes to the following registers:
UARTLCR_H Defines the:
Transmission parameters
Word length
Buffer mode
Number of transmitted stop bits
Parity mode
Break generation.
UARTIBRD defines the integer baud rate divider
UARTFBRD defines the fractional baud rate divider
Fractional baud rate divider
The baud rate divisor is a 22-bit number consisting of a 16-bit integer and a 6-bit fractional part. This is used by
the baud rate generator to determine the bit period. The fractional baud rate divider enables the use of any clock
with a frequency > 3.6864 MHz to act as UARTCLK, while it is still possible to generate all the standard baud
rates.
SAMSUNG

cn / louishan at 2015.01.13
The 16-bit integer is written to the Integer Baud Rate Register, UARTIBRD. The 6-bit fractional part is written to
the Fractional Baud Rate Register, UARTFBRD. The Baud Rate Divisor has the following relationship to
UARTCLK:
Baud Rate Divisor = UARTCLK/(16 Baud Rate) = BRDI + BRDF
Where BRDI is the integer part and BRDF is the fractional part separated by a decimal point as Figure 24-3
shows.

Baud rate divisor
You can calculate the 6-bit number (m) by taking the fractional part of the required baud rate divisor and
multiplying it by 64 (that is, 2n, where n is the width of the UARTFBRD Register) and adding 0.5 to account for
rounding errors:
m = integer(BRDF 2n + 0.5)

An internal clock enable signal, Baud16, is generated, and is a stream of one UARTCLK wide pulses with an
average frequency of 16 times the required baud rate. This signal is then divided by 16 to give the transmit clock.
A low number in the baud rate divisor gives a short bit period, and a high number in the baud rate divisor gives
along bit period.
Data transmission or reception
Data received or transmitted is stored in two 32 byte FIFOs, though the receive FIFO has an extra four bits per
character for status information.
For transmission, data is written into the transmit FIFO. If the UART is enabled, it causes a data frame to start
transmitting with the parameters indicated in the Line Control Register, UARTLCR_H. Data continues to be
transmitted until there is no data left in the transmit FIFO. The BUSY signal goes HIGH as soon as data is written
to the transmit FIFO (that is, the FIFO is non-empty) and remains asserted HIGH while data is being transmitted.
BUSY is negated only when the transmit FIFO is empty, and the last character has been transmitted from the shift
register, including the stop bits. BUSY can be asserted HIGH even though the UART might no longer be enabled.
For each sample of data, three readings are taken and the majority value is kept. In the following paragraphs the
middle sampling point is defined, and one sample is take neither side of it.
When the receiver is idle (UARTRXD continuously 1, in the marking state) and a LOW is detected on the data
input (a start bit has been received), the receive counter, with the clock enabled by Baud16, begins running and
data is sampled on the eighth cycle of that counter in UART mode, or the fourth cycle of the counter in SIR mode
to allow for the shorter logic 0 pulses (half way through a bit period).
The start bit is valid if UARTRXD is still LOW on the eighth cycle of Baud16, otherwise a false start bit is detected
and it is ignored.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
If the start bit was valid, successive data bits are sampled on every 16th cycle of Baud16 (that is, one bit period
later) according to the programmed length of the data characters. The parity bit is then checked if parity mode was
enabled.
Lastly, a valid stop bit is confirmed if UARTRXD is HIGH, otherwise a framing error has occurred. When a full
word is received, the data is stored in the receive FIFO, with any error bits associated with that word.
Error bits
Three error bits are stored in bits[10:8] of the receive FIFO, and are associated with a particular character. There
is an additional error that indicates an overrun error and this is stored in bit 11 of the receive FIFO.
Overrun bit
The overrun bit is not associated with the character in the receive FIFO. The overrun error is set when the FIFO is
full, and the next character is completely received in the shift register. The data in the shift register is overwritten,
but it is not written into the FIFO. When an empty location is available in the receive FIFO, and another character
is received, the state of the overrun bit is copied into the receive FIFO along with the received character. The
overrun state is then cleared. Table 24-1 lists the bit functions of the receive FIFO.

Disabling the FIFOs
Additionally, you can disable the FIFOs. In this case, the transmit and receive sides of the UART have 1-byte
holding registers (the bottom entry of the FIFOs). The overrun bit is set when a word has been received, and the
previous one was not yet read. In this implementation, the FIFOs are not physically disabled, but the flags are
manipulated to give the illusion of a 1-byte register. When the FIFOs are disabled, a write to the data register
bypasses the holding register unless the transmit shift register is already in use.
System and diagnostic loopback testing
You can perform loopback testing for UART data by setting the Loop Back Enable (LBE) bit to 1 in the Control
Register, UARTCR.
Data transmitted on UARTTXD is received on the UARTRXD input.

IrDA SIR operation
The IrDA SIR ENDEC provides functionality that converts between an asynchronous UART data stream, and halfduplex serial SIR interface. No analog processing is performed on-chip. The role of the SIR ENDEC is to provide a
digital encoded output, and decoded input to the UART. There are two modes of operation:
In IrDA mode, a zero logic level is transmitted as high pulse of 3/16th duration of the selected baud rate bit
period on the nSIROUT signal, while logic one levels are transmitted as a static LOW signal. These levels
control the driver of an infrared transmitter, sending a pulse of light for each zero. On the reception side, the
incoming light pulses energize the photo transistor base of the receiver, pulling its output LOW. This drives the
SIRIN signal LOW.
In low-power IrDA mode, the width of the transmitted infrared pulse is set to three times the period of the
internally generated IrLPBaud16 signal (1.63µs, assuming a nominal 1.8432MHz frequency) by setting the
SIRLP bit in the Control Register, UARTCR.
In normal and low-power IrDA modes:
During transmission, the UART data bit is used as the base for encoding
During reception, the decoded bits are transferred to the UART receive logic

The IrDA SIR physical layer specifies a half-duplex communication link, with a minimum 10 ms delay between
transmission and reception. This delay must be generated by software because it is not supported by the UART.
The delay is required because the Infrared receiver electronics might become biased, or even saturated from the
optical power coupled from the adjacent transmitter LED. This delay is known as latency, or receiver setup time.
The IrLPBaud16 signal is generated by dividing down the UARTCLK signal according to the low-power divisor
value written to the IrDA Low-Power Counter Register, UARTILPR.
The low-power divisor value is calculated as:
Low-power divisor = (FUARTCLK/FIrLPBaud16)
where FIrLPBaud16 is nominally 1.8432 MHz
The divisor must be chosen so that 1.42 MHz < FIrLPBaud16< 2.12 MHz.
System and diagnostic loopback testing
It is possible to perform loopback testing for SIR data by:
Setting the LBE bit to 1 in the Control Register, UARTCR.
Setting the SIRTEST bit to 1 in the Test Control Register, UARTTCR.
Data transmitted on nSIROUT is received on the SIRIN input.

24.4.7 UART DMA Interface
The UART provides an interface to connect to a DMA controller. The DMA operation of the UART is controlled
using the DMA Control Register, UARTDMACR. The DMA interface includes the following signals:
For receive:
UARTRXDMASREQ
Single character DMA transfer request, asserted by the UART. For receive, one character consists of up to 12
bits. This signal is asserted when the receive FIFO contains at least one character.
UARTRXDMABREQ
Burst DMA transfer request, asserted by the UART. This signal is asserted when the receive FIFO contains more
characters than the programmed watermark level. You can program the watermark level for each FIFO using the
Interrupt FIFO Level Select Register, UARTIFLS.
UARTRXDMACLR
DMA request clear, asserted by a DMA controller to clear the receive request signals. If DMA burst transfer is
requested, the clear signal is asserted during the transfer of the last data in the burst.
For transmit:
SAMSUNG
Confidential
cn / louishan at 2015.01.13
UARTTXDMASREQ
Single character DMA transfer request, asserted by the UART. For transmit one character consists of up to eight
bits. This signal is asserted when there is at least one empty location in the transmit FIFO.
UARTTXDMABREQ
Burst DMA transfer request, asserted by the UART. This signal is asserted when the transmit FIFO contains less
characters than the watermark level. You can program the watermark level for each FIFO using the Interrupt FIFO
Level Select Register, UARTIFLS.
UARTTXDMACLR
DMA request clear, asserted by a DMA controller to clear the transmit request signals. If DMA burst transfer is
requested, the clear signal is asserted during the transfer of the last data in the burst.
The burst transfer and single transfer request signals are not mutually exclusive, they can both be asserted at the
same time. For example, when there is more data than the watermark level in the receive FIFO, the burst transfer
request and the single transfer request are asserted. When the amount of data left in the receive FIFO is less than
the watermark level, the single request only is asserted. This is useful for situations where the number of
characters left to be received in the stream is less than a burst.
For example, if 19 characters have to be received and the watermark level is programmed to be four. The DMA
controller then transfers four bursts of four characters and three single transfers to complete the stream.
NOTE: For the remaining three characters the UART cannot assert the burst request.

Each request signal remains asserted until the relevant DMACLR signal is asserted. After the request clear signal
is de-asserted, a request signal can become active again, depending on the conditions described previously. All
request signals are de-asserted if the UART is disabled or the relevant DMA enable bit, TXDMAE or RXDMAE, in
the DMA Control Register, UARTDMACR is cleared.
If you disable the FIFOs in the UART then it operates in character mode and only the DMA single transfer mode
can operate, because only one character can be transferred to, or from the FIFOs at any time.
UARTRXDMASREQ and UARTTXDMASREQ are the only request signals that can be asserted. See the Line
Control Register, UARTLCR_H for information about disabling the FIFOs.
When the UART is in the FIFO enabled mode, data transfers can be made by either single or burst transfers
depending on the programmed watermark level and the amount of data in the FIFO. Table 24-3 lists the trigger
points for UARTRXDMABREQ and UARTTXDMABREQ depending on the watermark level, for the transmit and
receive FIFOs.

UARTPEINTR, because of a parity error in the received character
UARTFEINTR, because of a framing error in the received character.

Provision of individual outputs and the combined interrupt output, enables you to use either a global interrupt
service routine, or modular device drivers to handle interrupts.
The transmit and receive dataflow interrupts UARTRXINTR and UARTTXINTR *have been separated from the
status interrupts. This enables you to use *UARTRXINTR* and *UARTTXINTR so that data can be read or written
in response to the FIFO trigger levels.
The error interrupt, UARTEINTR, can be triggered when there is an error in the reception of data. A number of
error conditions are possible.
The modem status interrupt, UARTMSINTR, is a combined interrupt of all the individual modem status signals.
The status of the individual interrupt sources can be read either from the Raw Interrupt Status Register, UARTRIS
or from the Masked Interrupt Status Register, UARTMIS.
UARTMSINTR
The modem status interrupt is asserted if any of the modem status signals (nUARTCTS, nUARTDCD,
nUARTDSR, and nUARTRI) change. It is cleared by writing a 1 to the corresponding bit(s) in the Interrupt Clear
Register, UARTICR, depending on the modem status signals that generated the interrupt.

UARTRXINTR
The receive interrupt changes state when one of the following events occurs:
If the FIFOs are enabled and the receive FIFO reaches the programmed trigger level. When this happens, the
receive interrupt is asserted HIGH. The receive interrupt is cleared by reading data from the receive FIFO until
it becomes less than the trigger level, or by clearing the interrupt.
If the FIFOs are disabled (have a depth of one location) and data is received thereby filling the location, the
receive interrupt is asserted HIGH. The receive interrupt is cleared by performing a single read of the receive
FIFO, or by clearing the interrupt.
UARTTXINTR
The transmit interrupt changes state when one of the following events occurs:
If the FIFOs are enabled and the transmit FIFO is equal to or lower than the programmed trigger level then the
transmit interrupt is asserted HIGH. The transmit interrupt is cleared by writing data to the transmit FIFO until
it becomes greater than the trigger level, or by clearing the interrupt.
If the FIFOs are disabled (have a depth of one location) and there is no data present in the transmitters single
location, the transmit interrupt is asserted HIGH. It is cleared by performing a single write to the transmit FIFO,
or by clearing the interrupt.

The UARTDR Register is the data register.
For words to be transmitted:
If the FIFOs are enabled, data written to this location is pushed onto the transmit FIFO
If the FIFOs are not enabled, data is stored in the transmitter holding register (the bottom word of the transmit
FIFO).
The write operation initiates transmission from the UART. The data is prefixed with a start bit, appended with
the appropriate parity bit (if parity is enabled), and a stop bit. The resultant word is then transmitted.
For received words:
If the FIFOs are enabled, the data byte and the 4-bit status (break, frame, parity, and overrun) is pushed onto
the 12-bit wide receive FIFO
If the FIFOs are not enabled, the data byte and status are stored in the receiving holding register (the bottom

The UARTILPR Register is the IrDA low-power counter register. This is an 8-bit read/write register that stores the
low-power counter divisor value used to generate theIrLPBaud16 signal by dividing down of UARTCLK.
The IrLPBaud16 signal is generated by dividing down the UARTCLK signal according to the low-power divisor
value written to the UARTILPR Register.
The low-power divisor value is calculated as follows:
low-power divisor (ILPDVSR) = (FUARTCLK/FIrLPBaud16)

where FIrLPBaud16 is nominally 1.8432 MHz.
You must select the divisor so that 1.42 MHz < FIrLPBaud16 < 2.12 MHz, results in a low-power pulse duration of
1.41-2.11 µs (three times the period of IrLPBaud16).

UARTTCR is set to 1, then the nSIROUT path is inverted,
and fed through to the SIRIN path. The SIRTEST bit in the
test register must be set to 1 to override the normal halfduplex SIR operation. This must be the requirement for
accessing the test registers during normal operation, and
SIRTEST must be cleared to 0 when loopback testing is
finished. This feature reduces the amount of external
coupling required during system test.
If this bit is set to 1, and the SIRTEST bit is set to 0, the
UARTTXD path is fed through to the UARTRXD path.
In either SIR mode or UART mode, when this bit is set, the
modem outputs are also fed through to the modem inputs.
This bit is cleared to 0 on reset, to disable loopback.

The interrupts are generated based on a transition through a level rather than being based on the level. That is,
the interrupts are generated when the fill level progresses through the trigger level.
The bits are reset so that the trigger level is when the FIFOs are at the half-way mark.

Description
USBVBUSIO
USB2.0 OTG module can operate in device mode when the voltage on USBVBUSIO is
valid. To be valid in device mode, the voltage on USBVBUSIO is required to be between
4.75 V and 5.25 V.
USBVBUS
When VBUSVLDEXTSEL of USB PHY register is set to 1, USBVBUS is used instead of
USBVBUSIO. The USBVBUS pad is a logic-level input. When the USB2 PHY is operating
as a device, The USBVBUS acts as a gating signal for many of the internal USB2 PHY
modules. Therefore, it is important that transitions on the USBVBUS are clean and welldefined.

The USB 2.0 PHY requires an off-chip charge pump to provide power to the USB 2.0 OTG PHY VBUS pin.
Figure 25-2 shows the charge pump connection to the USB 2.0 PHY.
The charge pump's output is connected directly to VBUS on the device board. The USB 2.0 PHY's VBUS pin
VBUS pin is also connected to VBUS. The charge pump's DRVVBUS input is an output of the OTG HNP
finitestate machine and an input to the USB 2.0 PHY.
The VBUS presents a worst-case core-side load of 500pF. This worst-case load is a small addition to the overall
capacitance budget that includes the external capacitive load due to routing, pads, package, board traces, and
receivers

25.5.5 Modes of Operation
The application operates the Link either in DMA mode or in Slave mode. The application cannot operate the core
using DMA and Slave modes simultaneously.
DMA Mode
USB OTG host uses the AHB Master interface to transmit packet data fetch (AHB to USB) and receive data
update (USB to AHB). The AHB master uses the programmed DMA address (HCDMAn register in Host mode
and DIEPDMAn/DOEPDMAn register in Device mode) to access the data buffers.
Slave Mode
USB OTG can operate either in transaction-level operation or in pipelined transaction-level operation. The
application handles one data packet at a time per channel/endpoint in transaction-level operations. In
pipelined transaction-level operation, the application programs the OTG to perform multiple transactions. The
advantage of pipelined operation is that the application is not interrupted on packet basis.

This interrupt is valid only in DMA mode. This interrupt

For example, after detecting an endpoint mismatch, the
application:

If the global non-periodic IN NAK is cleared, the core has

received: the core generates an "IN token received when
FIFO empty'' interrupt. The OTG then sends the host a NAK
response. To avoid this scenario, the application checks the
GINSTS. FetSusp interrupt, which ensures that the FIFO is
full before clearing a global NAK handshake.
Alternatively, the application masks the “IN token received
when FIFO empty” interrupt if clearing a global IN NAK
handshake.

26.1 Overview
The USB 2.0 EHCI Host Controller is fully compliant with the USB 2.0 specification and the Enhanced Host
Controller Interface (EHCI) specification (revision 2.0). The controller supports high-speed, 480Mbps transfers (40
times faster than USB 1.1 full- speed mode) as well as companion controller integration with the USB 1.1OHCI
Host Controller. The controller is designed to operate independently of the Bus Interface Unit (BIU) to the
Application, shielding the complexities of the USB 2.0 Host Controller native protocol and providing easy
integration of the EHCI Host Controller with an industry-standard AHB or PCI bus or with your target application.
At the USB 2.0 physical interface, the EHCI Host Controller is designed with USB 2.0 Transceiver Macro cell
Interface. Also the controller provides High-Speed Inter-Chip (HSIC) (version 1.0).

27.1 Overview
The I2S controller supports streaming serial audio data between the External I2S Codec (ADC/DAC) and the
processor. It consists of one transmitter channel and one receive channel. Both the transmitting and receiving
channels are independent of each other and can work simultaneously.
The I2S controller interface can be configured to work in three modes by the IMS (Internal Master/Slave)
Fields in the I2SMOD register.
Internal Master mode
In the Internal master mode the Clock source to the I2S controller is APB "PCLK". The Bit Clock
"I2SBCLK"' and the word select signal "I2SLRCLK" is generated internally from PCLK.
External Master mode
In the External master mode, the Clock source to the I2S controller is External Codec Clock. The Bit Clock
"I2SBCLK" and the word select signal "I2SLRCLK" is generated internally from PCLK.
Slave mode
In the Slave mode, the Clock source to the I2S controller is APB "PCLK". The Bit Clock "I2SBCLK" and
the word select signal "I2SLRCLK" is also supplied to the I2S Controller from an External source.

27.4 Functional Description
The I2S Controller is very feature rich and works in slave only and External master and internal master mode as
Transmitter or Receiver. In the Master mode, the Output Codec Clock to the External codec and the BCLKm is
generated by the I2SLKCON block. The Audio Channel Clock is then derived from the BCLKm in the I2S Channel
generator Block.
In the Slave Mode BITCLK and LRCLK is supplied from an external master.
The I2S controller after the power on reset needs to be configured for I2S Access. The Configuration block is
I2SREG block. Here using the APB access the TX and Receive FIFO needs to be flushed before any valid I2S
Transaction can occur. Then I2S Data is written using the PWRITE and PWDATA APB signals, which are written
onto the TXFIFO block .For the I2S to transmit, the I2SACTIVE Signal should be activated for the TXFIFO block to
transfer the data onto I2S Channel Generator Block.
The I2S Channel Generator Block then takes the BITCLK and generates the Channel Clock and the Parallel to
serial load transfer control signals to the TX SFTR Block. The Holding Register inside the TX SFTR holds the
incoming Parallel data and passes it onto I2SSDO bit by bit aligned with BITCLK. The Channel Clock LRCLK is
also passed along with Channel Clock enable.
During the Receive phase, the change on Channel clock is interpreted as the incoming data on the I2SSDI line
and is latched in on the positive edge of BCLK inside the RX SFTR.
The I2SACTIVE with the help of BCLK and LRCLK help generate the control signal, Serial to Parallel load in the
Channel generator block. The Channel Generator block waits for the Left Channel data and the Right Channel
data and passes it onto the RX FIFO Block where it is stored in subsequent locations .Any read from the APB is
then provided the stored data.

cn / louishan at 2015.01.13
The DMA Access to the I2S Controller can be activated by enabling the TXDMACTIVE/RXDMACTIVE bit in the
I2SREG block. The TXDREQ is generated in the TXDMAFSM Block when TXDMACTIVE is high and the TXFIFO
is not full .The RXDREQ is generated in the RXDMAFSM when the RXDMACTIVE is high and the RX FIFO is not
empty. Both requests work on a Request -ACK mode.

27.4.2 I2S-bus Format
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The I2S bus has four lines including serial data input I2SSDI, serial data output I2SSDO, left/right channel select
clock I2SLRCLK, and serial bit clock I2SBCLK; the device generating I2SLRCLK and I2SBCLK is the master.
Serial data is transmitted in 2's complement with the MSB first with a fixed position, whereas the position of the
LSB depends on the word length. The transmitter sends the MSB of the next word at one clock period after the
I2SLRCLK is changed. Serial data sent by the transmitter may be synchronized with either the trailing or the
leading edge of the clock signal. However, the serial data must be latched into the receiver on the leading edge of
the serial clock signal, and so there are some restrictions when transmitting data that is synchronized with the
leading edge.
The LR channel select line indicates the channel being transmitted. I2SLRCLK may be changed on either a
trailing or leading edge of the serial clock, but it does not need to be symmetrical. In the slave, this signal is
latched on the leading edge of the clock signal. The I2SLRCLK line changes one clock period before the MSB is
transmitted. This allows the slave transmitter to derive synchronous timing of the serial data that will be set up for
transmission. Furthermore, it enables the receiver to store the previous word and clear the input for the next word.
MSB (Left) Justified
MSB-Justified (Left-Justified) format is similar to I2S bus format, except the in MSB-justified format, the
transmitter always sends the MSB of the next word at the same time whenever the I2SLRCLK is changed.
LSB (Right) Justified
LSB-Justified (Right-Justified) format is opposite to the MSB-justified format. In other word, the transferring
serial data is aligned with ending point of I2SLRCLK transition.

27.5 Programming Guide
27.5.1 Tx Channel
The I2S TX channel provides a single stereo compliant output. The transmit channel can operate in master or
Slave mode. Data is transferred between the processor and the I2S controller via an APB access or a DMA
access.
The processor must write words in multiples of two (i.e. for left and right audio sample). The words are serially
shifted out timed with respect to the audio bit clock, BCLK and word select clock, LRCLK.
TX Channel has 16 32 bit wide FIFO where the processor or DMA can write up to 16 left/right data samples after
enabling the channel for transmission.
An Example sequence is as the following.
Ensure the PCLK and CODCLKI are coming correctly to the I2S controller and FLUSH the TX FIFO using the
TFLUSH bit in the I2SFIC Register (I2S FIFO Control Register).
Please ensure that I2S Controller is configured in one of the following modes.
TX only mode
TX/RX simultaneous mode.
This can be done by programming the TXR bit in the I2SMOD register (I2S mode register).
SAMSUNG

Then program the following parameters according the need.
IMS
SDF
BFS
BLC
LRP
For programming, the above-mentioned fields please refer I2SMOD register (I2S mode register).
Once ensured that the input clocks for I2S controller are up and running and step 1 and 2 have been completed
we can write to TX FIFO.
The write to the TX FIFO has to be carried out thorough the I2STXD Register (I2S TX FIFO Register). This 32-bit
data will occupy position 0 of the FIFO and any further data will be written to position 2, 3 and so on.

Once the data is written to the TX FIFO the TX channel can be made active by enabling the I2SACTIVE bit in the
I2SCON Register (I2S Control Register).The data is then serially shifted out with respect to the bit clock BCLK and
word select clock LRCLK.
The TXCHPAUSE in the I2SCON Register (I2S Control Register) can stop the serial data transmission on the
I2SSDO.The transmission is stopped once the current Left/Right channel is transmitted. If the control registers in
the I2SCON Register (I2S Control Register) and I2SMOD Register (I2S Mode Register) are to be reprogrammed
then it is advisable to disable the TX channel.
If the TX channel is enabled while the FIFO is empty, no samples are read from the FIFO. The Status of TX FIFO
can be checked by checking the bits in the I2SFIC Register (I2S FIFO Control Register).

27.5.2 Rx Channel
The I2S RX channel provides a single stereo compliant output. The receive channel can operate in master or
slave mode. Data is received from the input line and transferred into the RX FIFO. The processor can then read
this data via an APB read or a DMA access can access this data.
RX Channel has a 16 32 bit wide RX FIFO where the processor or DMA can read up to 16 left/right data
samples after enabling the channel for reception.
An Example sequence is as following.
Ensure the PCLK and CODCLKI are coming correctly to the I2S controller and FLUSH the RX FIFO using the
RFLUSH bit in the I2SFIC Register (I2S FIFO Control Register) and the I2S controller is configured in any of the
modes.

Once ensured that the input clocks for I2S controller are up and running and step1 and 2 have been completed
user must put the I2SACTIVE high to enable any reception of data, the I2S controller receives data on the LRCLK
change.
The Data must be read from the RX FIFO using the I2SRXD Register (I2S RX FIFO Register) only after looking at
the RX FIFO count in the I2SFIC Register (I2S FIFO Control Register). The count would only increment once the
complete left channel and right have been received.

27.5.4 Notes
While doing continuous change in mode such as a TX only mode/RX only mode/TX-RX mode in a single test
kindly, ensure that the I2SACTIVE is only pulled low when a complete channel has been transmitted or in between
the change of modes a system reset occurs.
The I2S controller should be supplied the BFS value according to the valid table even in the slave mode for
correct functioning of the I2S unit.
The flush bit for the TX and RX FIFO should be given at the start of configuration of the I2S controller and not
anywhere in between for correct functioning of the device.
Always keep LRP = 1 for MSB and LSB justified mode in both Slave and Master mode.
While doing changes in TXDMAACTIVE/RXDMAACTIVE/I2SACTIVE/TXDMA PAUSE/RXDMA
PAUSE/TXCHANNEL PAUSE/RXCHANNEL PAUSE/TXR in 24-bit BLC configuration, ensure that Left and Right
channel data is transmitted or received successfully. Successful transmission or reception of Left and Right
channel data in 24-bit BLC configuration can be observed by polling LRI bit in I2SCON register.

28.1 Overview
The AC97 Controller Unit in the S5P4418 supports the features of AC97 revision 2.0. AC97 Controller uses audio
controller link (AC-link) to communicate with AC97 Codec. Controller sends the stereo PCM data to Codec. The
external digital-to-analog converter (DAC) in the Codec converts the audio sample to an analog audio waveform.
Controller receives the stereo PCM data and the mono MIC data from Codec then store in memories. This Section
describes the programming model for the AC97 Controller Unit. The prerequisite in this Section requires an
understanding of the AC97 revision 2.0 specifications.
28.2 Features
The AC97 Controller includes the following features:

28.4.2 Operation Flow Chart
When you initialize the AC97 controller, you must assert system reset or cold reset, because the previous state of
the external AC97 audio-codec is unknown. This assures that GPIO is already ready. Then you enable the codec
ready interrupt. You can check codec ready interrupt by polling or interrupt. When interrupt occurs, you must deassert codec ready interrupt. Use DMA or PIO (directly to write data to register) to transmit data from memory to
register or from register to memory. If internal FIFOs (Tx FIFO or Rx FIFO) are not empty, then let data be
transmitted.

28.4.3 AC-link Digital Interface Protocol
Each AC97 Codec incorporates a five-pin digital serial interface that links it to the S5P4418 AC97 Controller. AClink is a full-duplex, fixed-clock and PCM digital stream. It employs a time division multiplexed (TDM) scheme to
handle control register accesses and multiple input and output audio streams. The AC-link architecture divides
each audio frame into 12 outgoing and 12 incoming data streams. Each stream has 20-bit sample resolution and
requires a DAC and an analog-to-digital converter (ADC) with a minimum 16-bit resolution.

Figure 28-4
Bi-directional AC-link Frame with Slot Assignments
Figure 28-4 shows the slot definitions supported by S5P4418 AC97 Controller. The S5P4418 AC97 Controller
provides synchronization for all data transaction on the AC-link.
A data transaction is made up of 256 bits of information broken into groups of 13 time slots and is called a frame.
Time slot 0 is called the Tag Phase and it is 16 bits long. The other 12 time slots are called the Data Phase. The
Tag Phase contains one bit that identifies a valid frame and 12 bits that identify the time slots in the Data Phase
that contain valid data. Each time slot in the Data Phase is 20 bits long. A frame begins when SYNC goes high.
The amount of time that SYNC is high corresponds to the Tag Phase. AC97 frames occur at fixed 48 kHz intervals
and are synchronous to the 12.288 MHz bit rate clock, BITCLK.
The controller and the Codec use the SYNC and BITCLK to determine when to send transmit data and when to
sample received data. A transmitter transfers the serial data stream on each rising edge of BITCLK and a receiver
samples the serial data stream on falling edges of BITCLK. The transmitter must tag the valid slots in its serial
data stream. The valid slots are tagged in slot 0. Serial data on the AC-link is ordered most significant bit (MSB) to
least significant bit (LSB). The Tag Phase's first bit is bit[15] and the first bit of each slot in Data Phase is bit[19].
The last bit in any slot is bit[0].

28.4.3.1 AC-link Output Frame (SDATA_OUT)
Slot 0: Tag Phase
In slot 0, the first bit is a bit (SDATA_OUT, bit[15]) which represents the validity of the entire frame. If
bit[15] is 1, the current frame contains at least a valid time slot. The next 12-bit positions correspond each
12 time slot contains valid data. Bits 0 and 1 of slot 0 are used as CODEC IO bits for I/O reads and writes
to the CODEC registers as described in the next section. In this way, data streams of differing sample rate
can be transmitted across AC-link at its fixed 48 kHz audio frame rate.
Slot 1: Command Address Port
In slot 1, it communicates control register address and write/read command information to the AC97
controller.
When software accesses the primary CODEC, the hardware configures the frame as follows:
o
In slot 0, the valid bit for 1, 2 slots are set.
o
In slot 1, bit[19] is set (read) or clear (write). Bits 18-12 (of slot 1) are configured to specify the index
to the CODEC register. Others are filled with 0's (reserved).
o
In slot 2, it configured with the data which is for writing because of output frame.
Slot 2: Command Data Port

Slot 3: PCM Playback Left channel*
Slot 3 is audio output frame is the composite digital audio left stream. If a sample has a resolution that is
less than 16 bits, the AC97 controller fills all training non-valid bit positions in the slot with zeroes.
Slot 4: PCM Playback Right channel
Slot 4 which is audio output frame is the composite digital audio right stream. If a sample has a resolution
that is less than 16 bits, the AC97 controller fills all training non-valid bit positions in the slot with zeroes.

28.4.3.2 AC-link Input Frame (SDATA_IN)
Each AC97 Codec incorporates a five-pin digital serial interface that links it to the S5P4418 AC97 Controller. AClink is a full-duplex, fixed-clock and PCM digital stream.
Slot 0: Tag Phase
In slot 0, the first bit (SDATA_OUT, bit[15]) indicates whether the AC97 controller is in the CODEC ready
state. If the CODEC Ready bit is 0, it means that the AC97 controller is not ready for normal operation.
This condition is normal after the power is de-asserted on reset and the AC97 controller voltage
references are settling.
Slot 1: Status Address Port/SLOTREQ bits
The status port monitors the status of the AC97 controller functions. It is not limited to mixer settings and
power management. Audio input frame slot 1s stream echoes the control register index for the data to be
returned in slot 2, if the controller tags slots 1 and 2 as valid during slot 0. The controller only accepts
status data if the accompanying status address matches the last valid command address issued during
the most recent read command. For multiple sample rate output, the CODEC examines its sample-rate
control registers, its FIFOs' states, and the incoming SDATA_OUT tag bits at the beginning of each audio
output frame to determine which SLOTREQ bits to set active (low). SLOTREQ bits asserted during the
current audio input frame indicate which output slots require data from the controller in the next audio
output frame. For fixed 48 kHz operation, the SLOTREQ bits are set active (low), and a sample is
transferred in each frame. For multiple sample-rate input, the "tag" bit for each input slot indicates whether
valid data is present.

28.4.4 AC97 Power-down
Figure 28-7
AC97 Power-Down Timing
28.4.4.1 Powering Down the AC-Link
The AC-link signals enter a low power mode when the AC97 Codec Power-down register (0x26) bit PR4 is set to 1
(by writing 0x1000). Then the Primary Codec drives both BITCLK and SDATA_IN to a logic low voltage level. The
sequence follows the timing diagram as shown in Figure 28-7.
The AC97 Controller transmits the write to Power-down register (0x26) via AC-link. Set up the AC97 Controller so
that it does not transmit data to slots 3-12 when it writes to the Power-down register bit PR4 (data 0x1000), and it
does not require the Codec to process other data when it receives a power down request. When the Codec
processes the request it immediately transfers BITCLK and SDATA_IN to a logic low level. The AC97 Controller
drives SYNC and SDATA_OUT to a logic low level after programming the AC_GLBCTRL register.

28.4.4.2 Waking Up the AC-Link - Wake Up Triggered by the AC97 Controller
AC-link protocol provides a cold AC97 reset and a warm AC97 reset. The current power-down state ultimately
dictates which AC97 reset is used. Registers must stay in the same state during all power-down modes unless a
cold AC97 reset is performed. In a cold AC97 reset, the AC97 registers are initialized to their default values. After
a power down, the AC-link must wait for a minimum of four audio frame times after the frame in which the power
down occurred before it can be reactivated by reasserting the SYNC signal. When AC-link powers up, Codec
ready bit (input slot 0, bit[15]) indicates that AC-link is ready for operation.

28.4.4.3 Cold AC97 Reset
A cold reset is generated when the nRESET pin is asserted through the AC_GLBCTRL. Asserting and deasserting nRESET activates BITCLK and SDATA_OUT. A cold reset initializes all of AC97 control registers.
nRESET is an asynchronous AC97 input.
28.4.4.4 Warm AC97 Reset
A Warm AC97 reset reactivates the AC-link without altering the current AC97 register values. A warm reset is
generated when BITCLK is absent and SYNC is driven high. In normal audio frames, SYNC is a synchronous
AC97 input. When BITCLK is absent, SYNC is treated as an asynchronous input used to generate a warm reset to
AC97.The AC97 Controller must not activate BITCLK until it samples SYNC low again. This prevents a new audio
frame being falsely detected.

interface to interconnect digital audio equipment in consumer and professional applications.
When you use a consumer digital processing environment in SPDIF standard, the SPDIF interface is primarily
intended to carry stereophonic programs, with a resolution of up to 20 bits per sample, an extension to 24 bits per
sample being possible.
When you use SPDIF in a broadcasting studio environment, the interface is primarily intended to carry
monophonic or stereophonic programs, at a 48 kHz sampling frequency and with a resolution of up to 24 bits per
sample; it can carry one or two signals sampled at 32 kHz.
In both cases, the clock references and auxiliary information are transmitted with the program. IEC60958 enables
the interface to carry software related data.

Components in SPDIF Transmitter:
APB interface block: This block defines register banks to control the driving of SPDIFOUT module and data
buffers to store linear or non-linear PCM data.
DMA interface block: This block requests DMA service to IODMA that depends on the status of data buffer
in APB Interface block.
Clock Generator block: This block generates 128 fs (sampling frequency) clock that is used in out_spdif
block from system audio clock (MCLK).
Audio_if_core block: This block acts as an interface block between data buffer and out_spdif block. Finitestate machine controls the flow of PCM data.
spdif_tx block: This block inserts burst preamble and executes zero-stuffing in the nonlinear PCM stream.
The spdif_tx module bypasses the linear PCM data.
out_spdif block: This block generates SPDIF format. It inserts 4-bit preamble, 16- or 20- or 24-bit data, userdata bit, validity bit, channel status bit, and parity bit into the appropriate position of 32-bit word. It modulates
each bit to bi-phase format.

SAMSUNG

cn / louishan at 2015.01.13
A frame is uniquely composed of two sub-frames. The transmission rate of frames corresponds exactly to the
source sampling frequency.
In the 2-channel operation mode, the time multiplexing transmits samples taken from both channels in consecutive
sub-frames.
The sub-frames related to channel 1 (left or "A" channel in stereophonic operation and primary channel in
monophonic operation) normally use preamble M. However, the preamble is changed to preamble B after every
192 frame. This unit, which is composed of 192 frames, defines the block structure that is used to organize the
channel status information. Sub-frames of channel 2 (right or "B" in stereophonic operation and secondary
channel in monophonic operation) always use preamble W.
In the single-channel operation mode in broadcasting studio environment, the frame format is identical to the 2channel mode. Data is carried only in channel 1. In the sub-frames allocated to channel 2, time slot 28 (validity
flag) should be set to logical "1" ("1" means not valid).

SPDIF Frame Format
29.4.1.2 Sub-frame Format (IEC 60958)
Each sub-frame is divided into 32 time slot, numbered from 0 to 31. Time slots 0 to 3 carry one of the three
permitted preambles. These are used to affect synchronization of sub-frames, frames, and blocks. Time slots 4 to
27 carry the audio sample word in linear 2's complement representation. Time slot 27 carries the most significant
bit. When a 24-bit coding range is used, the least significant bit is in time slot 4.
When a 20-bit coding range is sufficient, the least significant bit is in time slot 8. Time slots 4 to 7 may be used for
other application. Under these circumstances, the bits in the time slots 4 to 7 are designated auxiliary sample bits.
If the source provides fewer bit than the interface allows (20 or 24 bits), the unused least significant bits shall be
set to a logical "0". This procedure supports that SPDIF connect equipment by using different numbers of bits.
Time slot 28 carries the validity flag associated with the audio sample word. This flag is set to logical "0" when the
audio sample is reliable. Time slot 29 carries 1 bit of the user data associated with the audio channel that is
transmitted in the same sub-frame. The default value of the user bit is logical "0".
Time slot 30 carries 1 bit of the channel status words associated with the audio channel transmitted in the same
sub-frame. Time slot 31 carries a parity bit such that the time slots, including 4 to 31 carries an even number of
ones and zeros.

29.4.3 Preamble
Preambles are specific patterns that provide synchronization and identification of the sub-frames and blocks. A set
of three preambles (M, B, and W) is used. These preambles are transmitted in the time allocated to four time slots
(time slots 0 to 3) and are represented by eight successive states. The first state of the preamble is always
different from the second state of the previous symbol.
Similar to bi-phase code, these preambles are dc free and provide clock recovery. They differ in minimum two
states from any valid bi-phase sequence.
29.4.4 Non-Linear PCM Encoded Source (IEC 61937)
The non-linear PCM encoded audio bit stream is transferred by using the basic 16-bit data area of the IEC 60958
sub frames, that is, in time slots 12 to 27. Each IEC 60958 frame can transfer 32 bits of the non-PCM data in
consumer application mode.
When the SPDIF bit stream conveys linear PCM audio, the symbol frequency is 64 times the PCM sampling
frequency (32 time slots per two channels of PCM sample time). When a non-linear PCM encoded audio bit
stream is transmitted by the interface, the symbol frequency shall be 64 times the sampling rate of the encoded
audio within that bit stream. If a non-linear PCM encoded audio bit stream is transmitted by the interface
containing audio with low sampling frequency, the symbol frequency shall be 128 times the sampling rate of the
encoded audio within that bit stream.
Each data burst contains a burst-preamble consisting of four 16-bit words (Pa, Pb, Pc, and Pd), followed by the
burst-payload, which contains data of an encoded audio frame.
SAMSUNG
Confidential
cn / louishan at 2015.01.13
The burst-preamble consists of four mandatory fields:
Pa and Pb represent a synchronization word.
Pc provides information about the type of data and some information/control for the receiver.
Pd provides the length of the burst-payload, limited to 216 (= 65,535) bits.
The four preamble words are contained in two sequential SPDIF frames. The frame beginning the data-burst
contains preamble word Pa in sub-frame 1 and Pb in sub-frame 2. The next frame contains Pc in sub-frame 1 and
Pd in sub-frame 2. When placed into a SPDIF sub-frame, the MSB of a 16-bit burst-preamble is placed into time
slot 27 and the LSB is placed into time slot 12.

29.4.5 SPDIF Operation
The bit frequency of SPDIF is 128 fs (fs: sampling frequency). Therefore, divide audio main clock (MCLK)
depending on the frequency of MCLK to make the main clock of SPDIF. You can divide MCLK by:
2 in case of 256 fs
3 in case of 384 fs
4 in case of 512 fs
The SPDIF module in Exynos5250 changes the audio sample data format to SPDIF. To change the format, SPDIF
module inserts these into the appropriate time slots:
Preamble data
Channel status data
User data
Error check bit
Parity bit
Preamble data are fixed in the module and inserted depending on sub-frame counter. Channel status data are set
in the SPDCSTAS register and used by 1 bit per frame. User data always have zero values.
For non-linear PCM data, insert burst-preamble, which consists of Pa, Pb, Pc, and Pd before burst-payload and
zero is padded from the end of burst-payload to the repetition count. Pa (= 16'hF872) and Pb (= 16'h4E1F) is fixed
in the module and Pc and Pd is set in the register SPDBSTAS. To stuff zero, the end of burst-payload is
calculated from Pd value and repetition count that depends on data type in the preamble Pc is acquired from
register SPDCNT.
SAMSUNG

cn / louishan at 2015.01.13
Audio data are justified to the LSB. 16-, 20- or 24-bit PCM data and 16-bit stream data are supported. The
unoccupied upper bits of 32-bit word are ignored.
Data are fetched via DMA request. When one of two data buffers is empty, DMA service is requested. Audio data
that are stored in the data buffers are transformed into SPDIF format and output to the port. For non-linear PCM
data, interrupt is generated after audio data are output up to the value specified in the SPDCNT register. Interrupt
sets the registers such as SPDBSTAS and SPDCNT to new values when the data type of new bit stream is
different from the previous one.

29.4.6 Shadowed Register
Both SPDBSTAS_SHD and SPDCNT_SHD registers are shadowed registers that are related to SPDBSTAS and
SPDCNT registers, respectively. They are updated from related registers at every stream end interrupt signal. The
usage of shadowed register is as follows.
1. Set burst status and repetition count information to their respective registers.
2. Turn on SPDIF module, and stream end interrupt is asserted immediately.
3. With stream end interrupt, shadowed registers are updated from their related registers and SPDIF starts to
transfer data.
4. The next stream information (burst status and repetition count) can be written to SPDBSTAS and SPDCNT
register because the previous information is copied to their respective shadowed registers.
5. Set next stream information to SPDBSTAS and SPDCNT registers.
6. Wait for stream end interrupt that signals the end of the first stream.
7. With stream end interrupt, the second stream data will start to transfer.
8. Set third stream information to registers.
The usage of user bit registers is similar to stream information registers. However, these registers are not related
to SPDIF end interrupt but to user data interrupt. As soon as SPDIF is on, the shadowed user bit registers are
updated from their related registers and user bit starts to be shifted out with asserted user data interrupt. User can
write the next user data to registers with this interrupt. After entire 96 user bits are shifted out, user data interrupt
will be asserted again and 3rd user bits can be written to registers with second user bits going out.

SPDIF RX
30.1 Overview
SPDIF standard defines a serial interface for transferring digital audio data between various audio equipment like
DVD/HD-DVD players, AVRs and amplifiers. When audio is transferred from a DVD player to an audio amplifier
over an analogue link, noise is introduced. Filtering out this noise is a difficult task. This problem is overcome
when audio data is transferred over a digital link instead of an analogue link. The data can be transferred between
devices without having to convert it to an analogue signal. This is the biggest advantage of SPDIF.
30.2 Features
Features of SPDIF-RX are:
Serial, unidirectional, self-clocking interface
Single wire-single signal interface

30.4 Functional Description
SPDIF is a single wire serial interface and the clock is embedded within the data. The transmitted data is bi-phase
mark encoded. The clock and frame sync is recovered at the receiver along with bi-phase decoded data stream.
Each data bit in the stream has a time slot. The time slot begins with a transition and ends with a transition. If the
transmitted data bit is "1" then additional transition is made in the middle of the time slot. Data bit "0" does not
have extra transition. The shortest interval between the transitions is called the unit interval (UI).
Figure 30-2
SPDIF Bi-phase Mark Encoded Stream
The least significant bit of the data is driven first. Each frame is 64 timeslots and has two sub-frames, which are 32
timeslots (Figure 30-3). The sub-frame starts with a preamble followed by 24 bits of data and ends with 4 bits
which carry information such as user data and channel status. The first four time slots of a sub-frame, called
preamble, is used to indicate sub-frame and block starts.

There are three preambles, each of which breaks the bi-phase coding rule by containing one or two pulses, which
have duration of 3 UIs. This would mean that the pattern can't occur anywhere else in the stream. Each sub-frame
begins with a 4-bit preamble. Start of a block is indicated by preamble "Z" and the start of sub-frame channel "A".
Preamble "X" indicates the start of a channel "A" sub-frame when not at the start of a block while preamble "Y"
indicates the start of a channel "B" sub-frame.

PDM
31.1 Overview
Pulse-density modulation (hereafter, PDM) is a form of modulation used to represent an analog signal with digital
data. In a PDM signal, specific amplitude values are not encoded into pulses of different size as they would be in
PCM. Instead, it is the relative density of the pulses that corresponds to the analog signal's amplitude. The output
of a 1-bit DAC is the same as the PDM encoding of the signal. The PDM in S5P4418 is a block that receives the
PDM signals from an exterior digital Microphone (with 1-bit IO) and demodulates the 1-bit digital signals and
returns original amplitude. The PDM supports DMA interface.
31.2 Features
Supports receiving 2 channel audio data with 1 data pin
1 output clock pin
2 data pins (total 4 channel accepts available)
Fixed output clock frequency
Supports select of the timing of data capture
Supports DMA interface
Supports a user configuration of Coefficient. (Butterworth Low-pass Filter)

33.4 Dual Register Set Architecture
The MLC of S5P4418 has dual register set architecture with a current working register group and a user side
register group. All users can set registers via the user side register group. If the dirty flag is set as "1" after the
user writes a desired setting to a register in the user side register group, the MLC copies the user side register
group to the current working register group at the point when vertical sync occurs. Then the dirty flag is cleared to
"0" and the user can continue to progress the next setting. In this way the changes in all registers are
synchronized and applied to vertical sync so that the user can hide any abnormal screen, even if the user changes
a register at any point.

33.5.1 Screen Size
The Screen size function enables users to specify the width and height of the whole screen to be displayed. The
values of "the whole screen width - 1" and "the whole height - 1" are set to the SCREENWIDTH and
SCREENHEIGHT, respectively. Since each of the SCREENWIDTH and SCREENHEIGHT has 12-bit size units,
the maximum available resolution is 2048 2048 pixels. The screen size is determined by setting the size in
frame units regardless of whether the display is progressive or interlace.
33.5.2 Priority
The MLC consists of three RGB layers and one Video layer. Among the RGB layers, Layer 0 has the highest
priority and Layer 1 has the lowest priority. These priorities cannot be changed, but the priority of the Video layer
can be adjusted via the PRIORITY parameter at the user's discretion.

33.5.3 Field Mode
The MLC of S5P4418 supports an interlace display as well as a progressive display. All registers of the MLC
should be set in frame units. For the progressive display, the FIELDENB bit of the Top controller should be set as
"0". For the interlace display, the FIELDENB bit of the Top controller should be set as "1". For example, a 720
480 progressive display and a 720 480 interlace display have the same settings, except for the setting of the
FIELDENB bit.
33.5.4 Background Color
Each layer of the MLC can be positioned at any place on the screen. Therefore, it is possible for there to be an
area not contained in any of the layers actually on the screen. The default color displayed in this area is called the
background color and the background color is set to BGCOLOR. If all layers are disabled, only the background
color is displayed on the screen.
The bpp of the BGCOLOR is 24 and has the following format:

Each layer has a LAYERENB bit to enable/disable each layer of S5P4418 at a certain point. If the LAYERENB bit
is set as "1", the relevant layer becomes on. If the LAYERENB bit is set as "0", the relevant layer becomes off and
the other layer setting registers are not used. Since the setting of the LAYERENB bit is reflected by a dirty flag, the
layer is toggled on/off in accordance with a VSYNC signal, even if the user controls the LAYERENB bit at a certain
point.

33.6.2 Lock Control
Each RGB layer can adjust the data size to be read at any one time when a memory read is requested through
the Lock control. The LOCKSIZE can specify 4, 8 or 16 and the unit size is 16 bytes. Therefore, if the LOCKSIZE
is 4, the data size to be read at any one time is 64 bytes. For a resolution of 1280 1024 or higher, it is
recommended to set the LOCKSIZE as 16.

only the layer contained in the area from (0, 0) and (ScreenWidth – 1, ScreenHeight – 1) is displayed on the actual
screen. The MLC of S5P4418 supports H/W clipping for any area outside of the screen area, so users do not need
to carry out additional clipping processing. In addition, the MLC does not read the data in the clipped area and the
area hidden by upper layer from memory for effective use of the memory bandwidth.

NOTE: The format settings for R8G8B8 & X8R8G8B8 and B8G8R8 & X8B8G8R8 are the same. However, the HSTRIDE*s
for R8G8B8 and B8G8R8 should be set as "3" because they are in 24 bpp modes, while the HSTRIDE*s for
X8R8G8B8 and X8B8G8R8 should be set as "4".
The above formats are converted into A8R8G8B8 and are managed in each RGB layer. Each color component is
converted into 8-bit size. The color components with the size smaller than 8-bit are extended to 8-bit size from the
highest bit repeatedly. For example, the color with 5-bit size is converted to {[4:0], [4:2]} and the color with 3-bit
size is converted to {[2:0], [2:0], [2:1]}. Each layer compares the color component internally extended with
TPCOLOR or INVCOLOR. Therefore, a user should set the color that each color format is extended in R8G8B8 in
TPCOLOR and INVCOLOR.

into RGB data are as follows:
The formula for YCbCr to RGB conversion
R = Y + (1.4020 Cr)
G = Y - (0.34414 Cb) + (0.71414 Cr)

Linear YUV 422 Format
The video layer supports the YUYV format as a linear YUV format whose Y data (luminance data) exists at
every pixel, but Cb and Cr (chrominance) data exist separately over two pixels. Therefore two pixels share the
same Cb/Cb data. Hence the Video layer has 2-pixel data per 32-bit and manages it in 2-pixel units.

In the 2D block addressing separated Y/U/V format, each of Y, U and V exists at separate memory spaces.
In addition, the format is divided into 444, 422 and 420 in proportion to U and V for Y. The 2D block
addressing separated YUV format is the 2D block addressing format, and each component has a size of
64 32 and linearity in block units. These features provide S5P4418s unique memory format, to enhance
the effectiveness of memory access when S5P4418 manages data in macro block units through an algorithm

33.6.4.3 Layer Blending
MLC consists of three RGB layers and one Video layer. Each RGB layer supports Transparency, Color Inversion
and Alpha Blending functions but the Video layer only supports Alpha Blending functions. The Color Inversion and
the Alpha Blending functions are only applied to between layers and not to background.
The Transparency function enables users to specify a particular color and handle the color as a transparent color.
Therefore, an area filled with a transparent color shows through the lower layer and shows the layer as it is. Like
the Transparency function, the Color Inversion function shows through the lower layer and shows the layer as it is,
but the function is different in that it inverts and projects the layer's color. The Transparency and Color Inversion
functions are useful for the implementation of the Cursor layer as shown in the figure below:

Transparency & Color Inversion
The Transparency and the Color Inversion effects are applied by setting each of the TPENB and the INVENB bits
of an RGB Layer as "1". Both TPCOLOR and INVCOLOR have R8G8B8 formats.

The Alpha Blending function enables users to adjust the transparency of a desired layer. The Alpha level is
adjusted by ALPHA[7:0] and can be specified in the range between 0 and 255. If the Alpha level is 255, it means it
is fully opaque. If the level is 0, it indicates full transparency. In addition, each RGB layer can use a pixel format
including Alpha and is applied in Alpha per pixel units. In the Per-layer alpha or the Per-pixel Alpha formats, the
Alpha Blending effect can only be applied by setting the BLENDENB bit as "1".
Only one layer can use the alpha blending function at the same time, and when the alpha blending function of one
layer is enabled, the alpha blending function of the other layers must be disabled.
All layers use the A8R8G8B8 format internally and the formula for Alpha Blending is as follows:

The formula for Alpha blending function
If alpha is 0 then α is 0, else is alpha + 1
Result color = this layer color / 256 + lower layer color (256 - ) / 256

The Address generation function enables users to specify the address and stride of the memory where images are
stored.
SAMSUNG

cn / louishan at 2015.01.13
Stride is divided into horizontal stride and vertical stride. The stride is the unit for increasing an address. The
horizontal stride (HSTRIDE) is the value to be added to an address whenever its x-coordinate increases, while the
vertical stride (VSTRIDE) is the value to be added to the address whenever its y-coordinate increases. In general,
the horizontal stride is the number of the bytes per pixel and the vertical stride is the value that is the number of
bytes per pixel multiplied by an image width. The vertical stride has 2's complement format. Thus a vertical flip
function can be implemented by specifying the vertical stride as negative number.
The Image address (ADDRESS) usually specifies an address on the top left corner of the image. If the vertical
stride for the vertical flip function has a negative number, the ADDRESS should specify an address on the bottom
left corner of the image.

33.6.5.2 Video Layer Address Generation
In the Video layer, the horizontal stride is not separately specified and is fixed internally. In addition, the vertical
stride should always be a positive number. Since the vertical stride is always positive number, the vertical flip
function is not supported.
Linear YUV 422 format (YUYV)
In the linear YUV 422 format, an address can only be specified by setting its base address and vertical stride.
The Base address (ADDRESS) specifies the base address in the YUYV image buffer and the vertical stride
(VSTRIDE) specifies the increment of the address in proportion to the increase of the y-coordinate.
The vertical stride should be a positive number.
2D block addressing separated YUV format
In the separated format, each Y, U and V is stored in different addresses of the memory. Thus the address
for the Y component is specified by the ADDRESS3 and the VSTRIDE3 registers and the address for the
U (Cb) and V (Cr) components is separately specified by the ADDRESSCB & the VSTRIDECB registers
and the ADDRESSCR& the VSTRIDECR registers. Since S5P4418 uses segments with 4096 4096 pixel
sizes in the 2D block addressing format, the vertical stride should be specified as 4096. In addition,
the ADDRESS3/CB/CR registers set the separate format for segment addresses and not for normal linear
addresses. The segment addressing format is listed in Table 33-10.

33.6.7 Scale Function
The scale-up and the scale-down of the Video layer are determined by the HSCALE and VSCALE parameters.
Each parameter finds and sets the ratio between an input image size and an output image size. The setting
formulae for the HSCALE and VSCALE parameters are as follows:
The formula for HSCALE and VSCALE
In case of the enlargement by using a Bilinear filter:
HSCALE = (source width-1) * (1<<11) / (destination width-1)
VSCALE = (source height-1) * (1<<11) / (destination height-1)
,else
HSCALE = source width * (1<<11) / destination width
VSCALE = source height * (1<<11) / destination height
Video Layer supports bilinear filtered scaling up and down. Nearest neighbor scaling is also supported. Filter
enable signals are separately allocated for Y and C (Cb, Cr) components in case of scaling up/down
(H/VFILTERENB, H/VFILTERENB_C)
When bilinear scaling up and down is used, H/VFILTERENB and H/VFILTERENB_C should be set to "1" for
bilinear filtered scaling. When nearest neighbor scaling down is used, H/VFILTERENB and H/VFILTERENB_C*
should be set to "0". The difference in images produced by the bilinear filter method is as shown in Figure 33-10.

33.6.7.1 Color Control
The Video layer supports the Color Control function for output images. A user can adjust Brightness, Contrast,
Hue and Saturation to compensate video data colors.
33.6.7.2 Luminance Enhancement
The Video layer can compensate luminance data by adjusting Brightness and Contrast.
The Brightness consists of 256 levels and is set by the BRIGHTNESS parameter. The BRIGHTNESS parameter
has a 2's complement value and can be set between the -128 level and the +127 level. Figure 33-11 shows the
image change depending on the Brightness change.

The Contrast consists of 8 levels and is set by the CONTRAST parameter. The Video layer can adjust the contrast
from 1.0 to 1.875 in increments of 0.125, but cannot reduce the contrast of the original image. Table 33-12 lists
the contrast values corresponding to the CONTRAST parameters.

33.6.7.3 Chrominance Enhancement
The Video layer can compensate Chrominance data by adjusting Hue and Saturation.
The Hue is adjusted by the following formulae:
(B-Y)' = (B-Y) Cos(θ) - (R-Y) Sin(θ)
(R-Y)' = (B-Y) Sin(θ) + (R-Y) Cos(θ)
The Saturation can be adjusted by multiplying a gain value by the above result value.
The Video layer can adjust the Hue and Saturation differently in each quadrant and has HUECBnA/B*and
*HUECRnA/B parameters for each quadrant. Each parameter has the [S.1.6] format and is applied as follows:

1st quadrant: (B-Y) > 0 and (R-Y) > 0
(B-Y)' = (B-Y) HUECB1A + (R-Y) HUECB1B
(R-Y)' = (B-Y) HUECR1A + (R-Y) HUECR1B
2.
2nd quadrant: (B-Y) < 0 and (R-Y) > 0
(B-Y)' = (B-Y) HUECB2A + (R-Y) HUECB2B
(R-Y)' = (B-Y) HUECR2A + (R-Y) HUECR2B
3.
3rd quadrant: (B-Y) < 0 and (R-Y) < 0
(B-Y)' = (B-Y) HUECB3A + (R-Y) HUECB3B
(R-Y)' = (B-Y) HUECR3A + (R-Y) HUECR3B
4.
4th quadrant: (B-Y) < 0 and (R-Y) < 0
(B-Y)' = (B-Y) HUECB4A + (R-Y) HUECB4B

Therefore, each parameter can be calculated by using the following formulas:
The formula for Hue and Saturation parameters:
HUECBnA = cos() * 64 * gain, HUECBnB = - sin() * 64 * gain
HUECRnA = sin() * 64 * gain, HUECRnB = cos() * 64 * gain
, where is for hue and gain is for saturation from -2 to 1.99999X.

33.6.8 Gamma Correction
MLC has three Gamma Table (256 10-bit) for Red, Green, and Blue colors. Gamma[9:0] consists of
Gamma[9:2], which are the integers(0 to 255), and Gamma[1:0], which are decimals (0.0, 0.5, 0.25, 0.75). And,
R10, G10, B10, as the result of Gamma correction, are transformed into R8, G8, B8, which then can be used as
input pixel for Display block , and it is possible to apply dithering while 10-bit results is being transformed into 8-bit.
Gamma correction can choose any Gamma region according to 3 different modes (total layer, RGB layer, Video
layer), and also can designate the Alpha-blended regions of Video layer and RGB layer as the region of RGB
layer or Video layer.
Gamma Table R = (255 * (R / 255) ^

33.7 Clock Generation
The MLC operates by using the PCLK and the BCLK. The PCLK is used when the CPU accesses the registers of
the MLC. The BCLK is used as an internal clock or when the MLC accesses the memory. The MLC provides
various operation modes for the PCLK and the BCLK. Therefore, users can adjust the clock for the MLC by setting
the PCLKMODE and the BCLKMODE parameters according to their purpose. Users must set Always Mode for
using the MLC. (BCLK and PCLK both)

Display Controller (DPC)
34.1 Overview
The Display controller (hereinafter, DPC) is a block that generates the signals to interface with external display
devices, such as a TFT-LCD, or video encoder. The DPC consists of a Sync generator. The Sync generator
transmits control signals to the Multi-Layer Controller (MLC) and receives RGB data from the MLC. Then the Sync
generator converts the received RGB data into a suitable format. In addition, the Sync generator can supports
various types of LCD and video encoders adjusting various output formats and Sync signals.
34.2 Features
Supports RGB, Multiplexed RGB (MRGB), ITU-R BT.601, ITU-R BT.656 and MPU Type (i80)
Programmable HSYNC, VSYNC and DE (Data Enable)
Programmable polarity for Sync signals
Programmable delay for data, Sync signals and clock phase
Supports UP-Scaler (Only Secondary Display)
Supports RGB dithering

34.4.1.2 Video Clock Generation
SAMSUNG

cn / louishan at 2015.01.13
Figure 34-4
Video Clock Generation
The DPC can create an output clock via various clock sources. The clocks for creating an output clock are 2-PLL,
PADCLK (P/SCLK, ACLK), etc.
The sync generator uses the VCLK and the VCLK2 as clock sources. The VCLK is a clock for the operation of a
pixel unit. The VCLK2 is a clock for pixel output. Therefore, the VCLK is one clock per pixel and the VCLK2 is 1 to
6 clocks per pixel depending on the output format. In the RGB and ITU-R BT.601A formats, which output one pixel
data per clock, the VCLK and the VCLK2 share the same clock. In the MRGB, the ITU-R BT.601B, the ITU-R
BT.601 (8-bit) and the ITU-R BT.656 formats, which output one pixel data per two clocks, the VCLK should divide
the VCLK2 by 2. Since the VCLK should divide the VCLK2 by 2, Clock Generator1 should use the output of Clock
Generator0 as the clock source. Users can select the output source by using the PADCLKSEL. The selection of
the PADCLKSEL is not related to the operation of the sync generator. In general, VCLK2 is used as the output
clock. If, however, a display device using a dual edge is connected, the VCLK is used as the output clock.

The DPC can adjust the polarity and phase of the output clock. The OUTCLKINV adjusts the polarity of the output
clock and the OUTCLKDELAY, OUTCLKSEL adjusts the phase of the output clock.
Basically, the DPC outputs data to be fetched at the falling edge and the OUTCLKINV is set as "0". For a display
device that fetches the clock at the rising edge, the OUTCLKINV should be set as "1" to invert the output clock.

34.4.2.1 RGB Format
In the RGB format, data are displayed in the order of blue components, green components and red components
based on the lower data. However, a user can swap the display of red components and blue components by
setting the SWAPRB as "1".
In addition, the DPC supports the Dithering effect in RGB format. All RGB data transmitted from the MLC have 8bit data width. Therefore, if the data width of each component is less than 8-bit, as in RGB565 and RGB666
display, the lower bits are discarded. In such cases, the display quality can be compensated by the Dithering
effect.
When RGB images are displayed as RGB565, the dithered image shows the difference from the image displayed,
as shown in Figure 34-7, after the unused lower bits are simply discarded.

34.4.2.2 YCbCr Format
Since the DPC only receives RGB data from the MLC, it outputs the data after converting the RGB data to YCbCr
data for the ITU-R BT.656 display or the ITU-R BT.601 display.
The DPC converts RGB data to YCbCr data by using the following formulae:
The formula for RGB to YCbCr conversion
Y= 0.229 R + 0.587 G + 0.114 B
Cb = – 0.169 R – 0.331 G + 0.5 B
Cr = 0.5 R – 0.419 G – 0.081 B
When ITU-R BT.601 B external display device is used, the user can change the data output order by adjusting the
YCORDER. The output data for YCORDER can be changed as listed in Table 34-6.

34.4.3 Sync Signals
The sync generator creates sync signals with various timings. The primary sync generator transmits HSYNC,
VSYNC and DE signals to the outside to provide timing interfaces for external display devices. Users can program
each sync signal setting to create the timings required from external display devices.
34.4.3.1 Horizontal Timing Interface
HSYNC and DE signals are used for Horizontal Sync. The horizontal timing consists of tHSW, tHBP, tHFP and
tAVW as shown in Figure 34-8.

The POLHSYNC is used to change the polarity of the HSYNC signal to be output to the outside. The horizontal
sync pulse is low active when the POLHSYNC is "0", while the horizontal sync pulse is high active when the
POLHSYNC is "1". The polarity of the Data Enable (DE) signal to be output to the outside cannot be changed and
the section that outputs valid data comes into high state.

In the ITU-R BT.656 format, SAV/EAV codes are inserted in data by setting the SEAVENB as "1". However, since
the SAV/EAV codes are transmitted via a data pin, the range of the data should be restricted, to distinguish the
codes from the data. Users can restrict the data range by using YCRANGE. Figure 34-12 shows that the result of
the color space conversion changing RGB data to YCbCr data varies depending on YCRANGE.

If YCRANGE is set as "0", a Y value between 0 and 15 is changed to 16 and a Y value between 236 and 255 is
changed to 235. In a similar way, Cb/Cr values between 0 and 15 are changed to 16 and Cb/Cr values between
241 and 255 are changed to 240. If YCRANGE is set as "1", all Y/Cb/Cr values are bypassed.

cn / louishan at 2015.01.13
The sync generator supports interlace display as well as progressive display. The Scan mode is determined by
SCANMODE. If SCANMODE is "0", the sync generator operates in progressive scan mode. If SCANMODE is "1",
the sync generator operates in interlaced scan mode. In interlaced scan mode, the different vertical timing
interfaces can be set in the odd and even fields separately. The odd field display and the progressive display
share same registers and registers for the even field display exists separately. Registers to create vertical timing
in accordance with the scan mode is listed in Table 34-13.

34.4.5 Delay
The pixel data is more delayed than the final output sync signal due to the processing in the sync generator.
Therefore, users should delay Sync signal output to synchronize the Sync signals with the pixel data. When the
Sync generator processes data, 4-clock is consumed for RGB data and 6-clock is consumed for YCbCr data.
Therefore, for synchronization between Sync signals and data, the output of the Sync signals should be delayed.
In RGB format and ITU-R BT.601A format with the same VCLK and VCLK2, delays of 4-clock and 6-clock should
be set in each format, separately. In the MGRB and the ITU-R BT.656/601B formats, where the VCLK2 is twice
the VCLK, delays of 8-clock and 12-clock should be set in each format, separately.

34.4.6 Interrupt
The DPC can generate an interrupt whenever VSYNC occurs.
Interrupt invokes each vertical Sync when TFT LCD Progressive operation. Interrupt invokes each 16 vertical sync
when STN LCD Progressive operation. Interrupt invokes each EVEN field (2 vertical sync) when interlace
operation. The DPC sets INTPEND as "1" if VSYNC occurs and notifies the interrupt generation to the Interrupt
controller if the INTENB is "1". Therefore, users can acknowledge the generation of VSYNC via polling by using
the status of the INTPEND regardless of the generation of interrupts. The INTPEND is cleared by writing "1" to it.

S5P4418 has register for communicating with external devices, and it supports 4 types of MPU interface format. In
the case of "writing", lower 16 bits need to be written to C010_2984 address followed by writing upper 8 bits to
C010_2990*address. In the case of "reading", upper 8 bits need to be read from *C010_298C address followed by
reading lower 16 bits from C010_2994 address. Actual communication with external devices is occurred when
writing to C010_2990*address and reading from *C010_298C address.

36.4.3 Skew Control between Output Data and Clock
The LVDS has the auto de-skew control function, If the LVDSCTRL0.I_AUTO_SEL and
*LVDSCTRL4.AUTO_DSK_SEL*are high. The LVDS could operate the de-skewing function automatically. For the
auto de-skewing, the signal which informs the vertical blank region is injected to the LVDS TX as like Figure 36-2.
If customer want to implement the auto de-skew function, RX have to support auto de-skew function.

37.1 Overview
The HDMI (High Definition Multimedia Interface) is compatible with HDMI v1.4 spec and supports up to 1080p
video resolution. It accepts RGB Video data from DPC and transmits them into HDMI cable with a serialized form.
The HDMI consists of a HDMI Link and HDMI PHY. The HDMI Link receives RGB Video data from DPC and
translates them into a sequence of 10-bit signals compliant to HDMI v1.4 specification. The HDMI PHY receives a
sequence of 10-bit signals from the HDMI Link and transmits them into HDMI cable with serialized form. And the
HDMI PHY can generate both pixel clock and TMDS clock from the reference 24 MHz clock. So users can use the
generated pixel clock from the HDMI PHY, instead of external divided PLL clock from CLKGEN.DPC (Display
Controller) also can use the generated pixel clock from the HDMI PHY. All the pixel clock frequency specified in
HDMI v1.4 spec can be generated by the HDMI PHY.

In S5P4418, users can choose one of two RGB Video data.
Primary DPC Video Data
Secondary DPC Video Data
When user want to use the Primary DPC Video Data for HDMI outputs, user set the HDMI_MUXSEL bit of the
HDMI_MUXCTRL register with 0 and set the HDMI_MUXENB bit of the HDMI_MUXCTRL register with 1.
37.4.2 HDMI Converter
The HDMI Converter converts the RGB Video data from DPC into a suitable format for the HDMI Link. Users must
set the HDMI Converter's parameters. The HDMI Converter consists of few registers. The configuration values for
the registers are in following table. The Figure 37-3 shows sync signal timing diagram.
NOTE: Since DPC makes sync signals, users must remember the sync information of current source video data. And users
must calculate the values of V2_BLANK and V_SYNC_LINE_BEF, etc. (referred on Figure 37-3)

37.4.3 HDMI LINK
The HDMI Link receives a converted Video Data from the HDMI Converter. Also, the HDMI link receives an audio
data from the SPDIFTX or I2S. The HDMI link translates them (video, audio) into a sequence of 10-bit signals
compliant to HDMI v1.4 specification.
Users must set the configuration about video and audio.
37.4.3.1 Video Input Interface
Video input interface receives i_vsync, i_h_active, i_field and pixel data signals to identify the starting of a frame,
the starting of a line and the starting of the top field in case of interlaced video formats. These signals, except for
the pixel data, are different from VSYNC, HSYNC and DE signals in the CEA-861. Note that HSYNC and DE
signal in CEA-861 are not used. Instead, actual vsync and hsync signals that are transferred to HDMI Rx side is
generated inside hdmi_14tx_ss according to the register settings.
The i_vsync signal is activated only one cycle during active area period of the last line of the previous
frame.i_h_active is always LOW as the blank period and HIGH during active period regardless of the video format.
Note that i_h_active goes HIGH even in the vertical blank period. Figure 37-4, Figure 37-5 show the timing
diagrams for the three signals.
There are two sets of the registers related to video timing. One specifies the input timing and the other specifies
the output timing. Video input/output timing with respect to the register values are also shown in Figure 37-4.Users
must set the input-related registers in accordance with the input video timing. Users can use the output-related
registers to control the video timing for display side, such as offset and display specific timing. Note that Figure
37-4 and Figure 37-5 is informative and is added to illustrate the relations between register values and video
timing. It is recommended referring to register descriptions for exact timing.

HPD signal has two transactions: rising (plugged) and falling (unplugged) transition. Users can specify the stage
number of the noise filter to reduce the possible glitches during transition.

37.4.3.4 CEC
CEC is abbreviation of Consumer Electronics Control and is used for controlling devices connected to a one-wired
"CEC bus". The CEC output port is a bidirectional port, which should be pulled-up to 3.3V using external resistor
and voltage supply. (i.e. an open-drain connection)
CEC devices send messages serially (MSB first) via CEC bus and the receiving device sends acknowledge bit by
pulling the bus to low at ACK bit timing. For timing of each bit and structure of a message, refer to HDMI
specification 1.4a, Supplement 1. (CEC specification)

37.4.3.5 Interrupt Timing
HDMI 1.4 Tx Subsystem generates level-triggered interrupts. Interrupts are masked in two levels: each sub
module and controller. On the other hand, interrupt clear happens only in sub module for all interrupts except
HPD. For HPD, every plug and unplug will generate, HPD plug interrupt and HPD unplug interrupt, respectively.
37.4.3.6 HDCP KEY Management
The HDMI can decrypt AES-encrypted HDCP key. For HDMI with HDCP function, each device should have a
unique HDCP key set. This key set is released by Digital Contents Protection. LLC (www.digital-cp.com).
HDCP key is stored outside of the HDMI Link at a non-volatile memory. It is important that the non-volatile
memory does not have original raw-HDCP. The key should be stored safely to prevent the key from
eavesdroppers.
The HDMI Link uses the AES encryption algorithm to protect plain HDCP key. Before starting the HDCP
authentication protocol, The HDMI Link reads encrypts HDCP keys from the memory (MEM_encr), decrypts the
keys using keys and stores the decrypted keys to decryption memory (MEM_decr). The decryption memory can
only be accessed by the HDCP engine inside the HDMI Link. The decryption memory cannot be accessed by
APB3 inter face to protect the decrypted keys. The AES key is supplied via ports (i_aeskey_data, i_aeskey_hw).
For the AES key, various chip id and fixed hardware value can be used. Note that only 128-bit key is supported.
The AES decryption starts by setting AES_Start bit of AES_START register. When the decryption is finished and
the decrypted keys are stored in the decryption memory, the AES_Start bit goes to 0, notifying the decryption is
done. The size of data to decrypt can be set by AES_DATA_SIZE_H/L register. After checking that AES_Start bit
is 0, decrypted data can be used for HDCP key. HDCP cannot operate until the AES_Start bit goes to 0.

When the shadow channel status registers are
updated, this bit is cleared.
Channel status information needs to be applied to the audio stream at the IEC 60958 block boundary. For this
synchronization, there are two register sets for channel status block. Users can set the channel status registers,
I2S_CH_ST_0 to I2S_CH_ST_4, while the I2S Rx module still refers to the shadow channel status registers,
I2S_CH_ST_SH_0 to I2S_CH_ST_CH4.To reflect the user configuration in the channel status registers, users
should set channel_status_reload bit in I2S_CH_ST_CON then I2S Rx module copies the channel status registers
into the shadow channel status registers at the beginning of an IEC-60958 block.

37.6.1 PHY Configuration Change through APB
The HDMI PHY has many internal registers to change its configuration, like pixel clock frequency or analog
characteristics. Users can access these registers through APB port. For secure configuration of the PHY core,
MODE_SET_DONE register (REG_7C<7>) is used for an indicator of APB setting state as shown in Figure 37-16.
(MODE_SET_DONE register is also controlled by APB.)
If users want store configure the HDMI PHY by new register setting, it should write 00h on MODE_SET_DONE
register (0xC010047C) instead of asserting overall RESET signal. Then PHY_READY signal goes to low state
and PHY waits for new register setting. After new values are written on PHY registers; MODE_SET_DONE
register should be set to 80h again letting PHY start to configure its state with new register values. Once
configuration is done, PHY_READY signal is automatically asserted.

37.6.2 PHY Ready Sequence
To assert PHY_READY signal, the HDMI PHY have to precede several steps shown in Figure 37-17. The HDMI
PHY core has a CMU and PCG for TMDS and pixel clock generation. Both of them should be locked and clock
de-skewing between TMDS_CLKHI and TMDS_CLKO should be finished before PHY_READY assertion. Thus,
TMDS_CLKHI should be supplied to PHY before PHY_READY signal assertion. The HDMI PHY ready sequence
is ignited by PHY_RESET signal which is external reset or in version of MODE_SET_DONE signal. Once
PLL_LOCK and CMU_LOCK signals go high, the de-skewing process starts. After de-skewing is finished, the
PHY_READY signal goes high meaning The HDMI PHY is ready to correctly send TMDS data.

37.6.3 HDMI PHY Configuration
Users need to set the HDMI PHY configuration to get a generated pixel clock. Following is a sequence of setting
the HDMI PHY configuration.
1. Set the HDMI CLKGEN's PCLKMODE with "1" (enable). (RESETREG[0].[10] release need.)
2. Set the TIEOFFREG[3].[0] with "1".
3. Release resets of RESETREG[0].[13] and RESETREG[0].[17] (HDMI PHY reset release).
4. Set the HDMI PHY's registers with Table 37-3 to generate a pixel clock
5. Check the *PHY_READY*bit of the *PHY_STATUS_0*register (HDMI Link) whether the HDMI PHY's
PHY_READY is HIGH.

38.3.1.2 Packet Header Arbitration
There are four-packet headers FIFOs for Tx, namely, main display, sub display, I80 INTERFACE command, and
SFR FIFO. The main and sub display FIFO packet headers contain the image data, while the I80 INTERFACE
command FIFO packet header contains the command packets. On the other hand, the SFR FIFO packet header
contains command packets, sub display image data (in Video mode), and so on.
The packet header arbiter has a "Fixed priority" algorithm. Priority order is fixed as main display, sub display, I80
INTERFACE command, and SFR FIFO packet header.
In the Video mode, sub display and I80 INTERFACE command FIFO are not used. The SFR FIFO packet header
checks if the main display FIFO is empty (no request) in not-active image region and then sends its request.

38.3.1.3 RxFIFO Structure
To read the packets received via low power data receiving mode, RxFIFO acts like an SFR. RxFIFO is an
asynchronous FIFO with ByteClk and PCLK domains as input clock and output clock domains respectively. The
Rx data is synchronized to RxClk. RXBUF has four Rx Byte buffers for aligning byte to word.
The packet headers of all the packets stored in RXFIFO are word-aligned, that is, the first byte of a packet is
always stored in LSB. For example, if a long packet has 7 byte payload, the last byte is filled with dummy byte and
the next packet is stored in the next word, as shown in Figure 38-3.
NOTE: CRC data is not stored in RXFIFO.

38.3.2.1 Display Controller Interface
MIPI DSI Master has two-display controller interfaces, namely, RGB INTERFACE for main display and CPU
INTERFACE (I80 INTERFACE) for main/ sub display. The Video mode uses RGB INTERFACE while the
Command mode uses CPU INTERFACE.
The RGB image data is loaded on the data bus of RGB INTERFACE and I80 INTERFACE with the same order:
RGB_VD[23:0] or SYS_VDOUT[23:0] is {R[7:0],G[7:0],B[7:0]}. Each byte aligns to the most significant bit. For
instance, in the 12-bit mode, only three 4-bit values are valid as R, G, and B each, that is, data[23:20],
data[15:12], and data[7:4]. The DSIM ignores rest of the bits.
38.3.2.2 RGB Interface
Vsync, Hsync, and VDEN are active high signals. Among the three signals, Vsync and Hsync are pulse types that
spend several video clocks. RGB_VD[23:0] is {R[7:0],G[7:0],B[7:0]}. All sync signals are synchronized to the rising
edge of RGB_VCLK. The display controller sends minimum one horizontal line length of Vsync pulse, V back
porch, and V front porch. Hsync pulse width should be longer than 1-byte clock cycle.

38.3.2.6 MIPI DSIM Converts RGB Interface to Video Mode
Vsync and Hsync packets are extremely important to protect image in Video mode. MIPI DSIM allows several
lines in VFP area to transfer general data transfer. As shown in Figure 38-13, the vertical front porch is divided
into three areas, namely, stable VFP area, command allowed area, and command masked area.
The register configures stable VFP area. Configuration boundary is 11'h000 to 11'h7FFF in DSIM_MVPORCH.
The register also configures the command allowed area. Configuration boundary is 4'h0 to 4'hF in
DSIM_MVPORCH. Only this area is allowed to start "command transfer" through HS mode or LPDT. In LPDT,
data transferring takes a long time to complete (approximately hundreds of microseconds or more). In this time,
Hsync packet does not arrive due to LPDT long packet. MIPI DSIM comprises of big size FIFO for lost Hsync
packet. After LPDT, MIPI DSIM transfers these Hsync packets immediately through HS mode.
To protect Vsync, command masked area is masked area. This area is calculated using LPDT bandwidth. For
example, if EscClk is 10 MHz, the maximum long packet payload size is 1KB and LPDT, LPDT transferring time is
824us (packet size: 1030 byte, LPDT maximum bandwidth: 10Mbps). If one line time is 20us, the line timing
violation occurs in 42 lines. Therefore, command masked area is larger than 42 + a. This "a" is transferring time of
the violated Hsync packets.
Display controller should be configured in such a way that VFP lines are sum of stable vfp, command allowed
area, and command masked area.

38.3.3 Configuration
Video Mode versus Command Mode
MIPI DSI Master Block supports two modes, namely, Video mode and Command mode.
38.3.4 PLL
To transmit Image data, MIPI DSI Master Block needs high frequency clock (80 MHz to 1 GHz) generated by PLL.
To configure PLL, MIPI DSI Master comprises of SFRs and corresponding interface signals. PLL is embedded in
PHY module. You should use other PLL in SoC if it meets the timing specification.
38.3.5 Buffer
In MIPI DSI standard specification, DSI Master sends image stream in burst mode. The image stream transmits in
high-speed and bit-clock frequency. This mode allows the device to stay in stop state longer to reduce power
consumption. For this mode, MIPI DSI Master has a dual line buffer to store one complete line and send it faster
at the next line time.

Dp and Dn of upper signals are D-phy channel of clock lane. RX_DDRCLKDIV2 is in PPI. BYTE_CLK is
generated clock that is generated in link layer (MIPI CSIS V3.0) and divided by 2 from RX_DDRCLKDIV2. Dp and
Dn of lower signals are D-phy channel of Data lane. Another signal of lower is PPI. STOP state (and
STOPstateClk) indicates that differential channel state of D-phy is LP11 (the voltage level of Dp and Dn is 1.2V)

38.5.1.2.3 ISP (CAM I/F) Interface
MIPI CSIS V3.0 output signals are PIX_CLK, VVALID, HVALID, and DATA. PIX_CLK is output pixel clock what is
generated from HCLK, BYTE_CLK or EXTCLK. VVALID is vertical sync signal. HVALID is horizontal sync signal.
DATA is image data bus. DATA bus width is dependent on Image format. Maximum bus width is 24 bits because
of RGB888. Figure 38-17 describes the output protocol of MIPI CSIS. All signals are synchronized with the rising
edge of PIX_CLK.

MIPI CSIS V3.0 has many interrupts for checking status, indicating error case and receiving generic data.
Odd_Before/Odd_After/Even_Before/Even_After
These interrupts are related with generic and embedded data.
Odd_Before and Odd_After interrupts are generated in odd frame. Even_Before and Even_After interrupts are
generated in even frame. Odd_Before and Even_Before interrupts are generated when Generic Short packet or
Embedded 8-bit based packet is received before image data (Vertical Back porch area)

38.5.4 Clock Specification
MIPI CSI may have 3 clock sources: RX_BYTE_CLK_HS0, I_PCLK, and I_WRAP_CLK.
I_PCLK
PCLK is system clock generated by general processor PLL.(APB clock)
RX_BYTE_CLK_HS0
This signal comes from data lane 0 of D-phy.
I_WRAP_CLK
I_WRAP_CLK is generated by clock generator. Refer to CSI clock in clock controller.

Block Diagram of Clock Domain
All clock domains are asynchronous each other. Pixel clock for transmitting image data to ISP is same with HCLK
or Wrapper clock.
The relationship between input and output bandwidth is that the output bandwidth should be faster than input
bandwidth. There is an equation of previous relationship:
(freq. of RX_BYTE_CLK_HS) (number of data lane) 8 bits (freq. of Pixel clock) (bitwidth of image format)

Analog Signal
Connect a 2nF capacitor between this pin and MS_VSS.
Place capacitor closely to chip.
Analog Signal
The peak current through DP and DN pads is 5.5 mA (0.44
V/80 ), for a maximum duty cycle of 4 % during a short-toground condition.
Make the total resistance of the package, ESD pad, and
pad-macro connection 0.5 to 1.0 .
To reduce inductance and via in an array-type package,
route these signals through shortest traces that reach outer
contacts of array.
Total capacitance of package, ESD pad, and pad-macro
connection should be < 2 pF.
Match delays of trace lines as close as possible to minimize
skew between CLK's and DATA's.
Require adjacent ball assignment to minimize intra-pair
differential signals skew.
Match CLK and DATA pairs for routing the path to minimize
intra-pair differential signals skew. Therefore, you should
consider symmetrical allocation for CLK and DATA pairs.

ITU-R BT.601 8-bit
The video input port has an 8-bit data bus and HSYNC and VSYNC pins, and supports ITU-R BT.601 8-bit input. If
the port uses an external HSYNC or VSYNC, the EXTSYNCENB bit should be set as "1". If the EXTSYNCENB bit
is "1", the port receives the HSYNC and VSYNC from the outside, and creates the HBLANK and VBLANK
internally. The polarity of the external H(V)SYNC only supports high active. Figure 39-4 shows the relationship
between the HBLANK and the VBLANK generated from external HSYNC and VSYNC inputs.

To create the HBLANK and VBLANK from the sync information contained in the data, the EXTSYNCENB should
be set as "0". The SAV/EAV decoder blocks generate the HBLANK and VBLANK from the sync information
contained in the data. The Sync Gen block generates the HSYNC and the VSYNC based on the HBLANK and
VBLANK signals. Figure 39-6 shows the relationship that generates the H(V)BLANK and H(V)SYNC from the

39.4.3 External Data Valid and Field
The video input port can receive data valid signals or field signals from the outside. Since the IDVALID and the
IFIELD share a pin, users can use only one of them.
External Data Valid
If the EXTDVENB is set as "1", users can use the input signal from the IFIELD/IDVALID pad as the IDVALID
signal. In this case, the polarity is determined by the DVALIDPOL. The video input port is designed to use the
IDVALID signal of active high mode internally. Therefore, if the polarity of an external IDVALID signal is active low,
the input signal should be inverted by setting the DVALIDPOL as "0". If the polarity of an external IDVALID signal
is active high, the input signal should be bypassed by setting the DVALIDPOL as 1.
Even though an external IDVALID signal is used, the internal HBLANK and VBLANK signals are used. Therefore,
the user should set the H(V)BEGIN and the H(V)END.
External Field
If an external field signal is used, the EXTFIELDENB should be set as 1. In the ITU-R BT.656 format, the input
signal from the IFIELD/IDVALID pad can be used as an external field signal by setting the EXTFIELDENB as "1".
The video input port internally considers it as an odd field if the polarity of the field signal is low. If the polarity of a
field signal is high, the port considers it as an even field. The user can select the polarity of a field signal by using
FIELDSEL, or can fix the polarity as "0 or "1".

Field Information
LASTFIELD is updated whenever a field signal is changed. In addition, when a VSYNC interrupt occurs, the user
can get the field status of the next data by using LASTFIELD. Since LASTFIELD is updated by using the PCLK,
the PCLK should be always enabled by setting the PCLKMODE as "1" to obtain a proper field status.
39.4.6 FIFO Controls
The video input port block can inform the user of the current status of the internal FIFO. The FIFOWRENB
indicates if data is being written to the FIFO. The FIFORDENB indicates if data is being read from the FIFO. If the
FIFO is empty, the FIFOEMPTY is set as "1". If the FIFO is full, the FIFOFULL is set as "1".
In addition, users can reset the FIFO at a specific point. According to the RESETFIFOSEL*setting, the reset point
of the FIFO can be controlled by selecting either FrameEnd (the end of VSYNC, *RESETFIFOSEL is "0"), Frame
Start (the start of vertical active video, RESETFIFOSEL is "1") or the RESETFIFO bit (RESETFIFOSEL is "2"), or
by selecting all of them (RESETFIFOSEL is "3"). The RESETFIFO bit is valid only when the RESETFIFOSEL*is
"2" or "3". If the FIFO is reset by setting the *RESETFIFO as "1", the RESETFIFO should be set as "0" again.

39.5.2 Output Data Format
The VIP can store input images in separated YUV format and linear YUV 4:2:2 format. The Clipper supports both
separated YUV format and linear YUV 4:2:2 format. If the YUYVENB is set as "0", data is stored in separated YUV
format. If the YUYVENB is set as "1", data is stored in linear YUV 4:2:2 format. The Decimator only supports
separated YUV format.
Linear YUV 4:2:2 format
Linear YUV format is the YUYV format, and Y (luminance) exists in each pixel. Cb and Cr (Chrominance)
separately exist in each of two pixels, and two pixels share the Cr and the Cb (Chrominance). The VIP has 2-pixel
information per 32-bit and is managed in 2-pixel units. Table 39-8 shows the memory format that Y/Cb/Cr data are
stored in.

The BASEADDRL(H)*and the*STRIDEL(H)*are used for the addressing of the linear YUV 4:2:2 format. The
*BASEADDR*is a 32-bit linear address, and specifies the memory address where output images from the Clipper
are stored. The *STRIDE is the memory offset from one scan line in the image buffer to the next. The STRIDE is
expressed in byte units and is also called pitch. If there is no-memory gap between lines in the image buffer, the
stride can be specified as CLIPWIDTH * 2.

The linear YUV 4:2:2 format is only supported by the Clipper, and YUYVENB should be set as "1".
Separated YUV format
In separated YUV format, each of Y, U and V exists at separate memory spaces. In addition, separated YUV
format is divided into 4:4:4, 4:2:2 and 4:2:0 in proportion to U and V for Y. Separated YUV format is the
addressing format, and each component has a size of 64 32 and linearity in block units. These features provide
the S5P4418's unique memory format, to enhance the effectiveness of memory access when the S5P4418
manages data in macro block units through an algorithm to compress/decompress images such as MPEG files.

40 Multi-Format Video Codec
Multi-Format Video Codec
40.1 Overview
The multi format video codec (hereinafter referred to as "VPU") is a full HD multi-standard video IP for consumer
multimedia products such as HDTVs, HD set-top boxes, and HD DVD players. It can decode compressed video in
a format of H.264 BP/MP/HP, VC-1 SP/MP/AP, MPEG-1/2, MPEG-4 SP/ASP, H.263P3, VP8,Theora, AVS, RV8/9/10, and JPEG (max. 8192 8192) It can also perform H.264, MPEG-4, and H.263 encoding up to Full-HD
1920 1088 (max. 8192 8192 JPEG) resolution. The VPU can perform simultaneous multiple real times
encoding, decoding, or both encoding and decoding of different format video streams at multiple resolutions.
The VPU contains a 16-bit DSP called BIT processor. The BIT processor communicates with a host CPU through
a host interface and controls the other sub-blocks of the VPU. The host CPU require slow resources under 1
MIPS, because all of the functions such as bit stream parsing, video hardware sub- blocks control and error
resilience are implemented in the BIT processor. Moreover it is designed to optimally share most of the sub-blocks
that are used in common for video processing, which contributes to the ultra low power and low gate count.
It is connected with a host CPU system via 32-bit AMBA 3 APB bus for system control and 128-bit AMBA3 AXI for
data. There are two 128-bit AXI buses: primary and secondary. The secondary bus can be connected to on-chip
memories to achieve high performance.
