8. UART Interface
BlueCore4-External Universal Asynchronous Receiver Transmitter (UART) interface
provides a simple mechanism for communicating with other serial devices using the RS232
standard(1).
BlueCore4-External
Figure 11.12: Universal Asynchronous Receiver
Four signals are used to implement the UART function, as shown in Figure 11.12. When
BlueCore4-External is connected to another digital device, UART_RX and UART_TX transfer
data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be
used to implement RS232 hardware flow control where both are active low indicators. All
UART connections are implemented using CMOS technology and have signalling levels of
0V and Vcc.
UART configuration parameters, such as Baud rate and packet format, are set using
BlueCore4-External software.

Notes:
In order to communicate with the UART at its maximum data rate using a standard PC,
an accelerated serial port adapter card is required for the PC.

Table 11.7: Possible UART Settings
The UART interface is capable of resetting BlueCore4-External upon reception of a
break signal. A Break is identified by a continuous logic low (0V) on the UART_RX terminal,
as shown in Figure 11.13. If tBRK is longer than the value, defined by the PS Key
PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur.
This feature allows a host to initialise the system to a known state. Also,
BlueCore4-External can emit a Break character that may be used to wake the Host.
Note:
The DFU boot loader must be loaded into the Flash device before the UART or USB
interfaces can be used.This initial flash programming can be done via the SPI.
Table 11.3 shows a list of commonly used Baud rates and their associated values for
the Persistent Store Key PSKEY_UART_BAUD_RATE (0x204). There is no requirement to use
these standard values. Any Baud rate within the supported range can be set in the
Persistent Store Key according to the formula in Equation 11.7.
Baud Rate = PSKEY_UART_BAUD_RATE / 0.004096

Table 11.8: Standard Baud Rates
8.1 UART Bypass
Figure 11.14: UART Bypass Architecture
8.2 UART Configuration While RESET is Active
The UART interface for BlueCore4-External while the chip is being held in reset is
tri-state. This will allow the user to daisy chain devices onto the physical UART bus.
The constraint on this method is that any devices connected to this bus must tri-state
when BlueCore4-External reset is de-asserted and the firmware begins to run.
8.3 UART Bypass Mode
Alternatively, for devices that do not tri-state the UART bus, the UART bypass mode
on BlueCore4-External can be used. The default state of BlueCore4-External after reset
is de-asserted, this is for the host UART bus to be connected to the BlueCore4-External
UART, thereby allowing communication to BlueCore4-External via the UART.
In order to apply the UART bypass mode, a BCCMD command will be issued to
BlueCore4-External upon this, it will switch the bypass to PIO[7:4] as shown in Figure
11.14. Once the bypass mode has been invoked, BlueCore4-External will enter the deep
sleep state indefinitely.
In order to re-establish communication with BlueCore4-External, the chip must be
reset so that the default configuration takes affect.
It is important for the host to ensure a clean Bluetooth disconnection of any active
links before the bypass mode is invoked. Therefore it is not possible to have active
Bluetooth links while operating the bypass mode.
8.4 Current Consumption in UART Bypass Mode
The current consumption for a device in UART Bypass Mode is equal to the values quoted
for a device in standby mode.
9. I/O Parallel Ports
Fifteen lines of programmable bi-directional input/outputs (I/O) are provided.
PIO[11:8] and PIO[3:0] are powered from Vcc. PIO[7:4] are powered from Vcc. AIO [2:0]
are powered from Vref.
PIO lines can be configured through software to have either weak or strong pull-ups
or pull-downs. All PIO lines are configured as inputs with weak pull-downs at reset.
PIO[0] and PIO[1] are normally dedicated to RXEN and TXEN respectively, but they
are available for general use.
Any of the PIO lines can be configured as interrupt request lines or as wake-up lines
from sleep modes. PIO[6] or PIO [2] can be configured as a request line for an external
clock source. This is useful when the clock to BlueCore4-External is provided from a
Chongqing JINOU Science and Technology Development Co., Ltd.
BTM4504C1H
Page 10
system application specific integrated circuit (ASIC).
BlueCore4-External has three general purpose analogue interface pins, AIO[0], AIO[1]
and AIO[2]. These are used to access internal circuitry and control signals. One pin
is allocated to decoupling for the on-chip band gap reference voltage, the other three
may be configured to provide additional functionality.
Auxiliary functions available via these pins include an 8-bit ADC and an 8-bit DAC.
Typically the ADC is used for battery voltage measurement. Signals selectable at these
pins include the band gap reference voltage and a variety of clock signals; 48, 24, 16,
8MHz and the XTAL clock frequency. When used with analogue signals the voltage range
is constrained by the analogue supply voltage (1.8V). When configured to drive out digital
level signals (clocks) generated from within the analogue part of the device, the output
voltage level is determined by Vref (1.8V).
Important Note:
CSR cannot guarantee that terminal functions PIOs remain the same. Please refer to
the software release note for the implementation of these PIO lines, as they are firmware
build specific.
10. RESETB
BlueCore4 Module may be reset from several sources: power on reset, a UART break
character or via a software configured watchdog timer.
The power on reset occurs when the VDD_CORE supply falls below typically 1.5V and
is released when VDD_CORE rises above typically 1.6V.
At reset the digital I/O pins are set to inputs for bi-directional pins and outputs
are tri-stated. The PIOs have weak pull-downs.
Following a reset, BlueCore4-External assumes the maximum XTAL_IN frequency, which
ensures that the internal clocks run at a safe (low) frequency until BlueCore4-External
is configured for the actual XTAL_IN frequency. If no clock is present at XTAL_IN, the
oscillator in BlueCore4-External free runs, again at a safe frequency.
10.1 Pin States on Reset
Table 11.15 shows the pin states of BlueCore4-External on reset.
