SieMo-S50037 Technical Description PRELIMINARYPage 15/294 Interface Description4.1 PCM Interface4.1.1 Overview PCM Pulse Code Modulation is astandard method used to digitisehuman voice Four-wire, full duplex serial interfaceused to transfer a single voice channelto an external audio codec Maximum of one SCO connection ispossible using the PCM interface Further SCO channels must use theHCI protocol layer Data format is 13 bit linear PCM4.1.2 DescriptionPulse Code Modulation (PCM) is thestandard method used to digitise humanvoice patterns for transmission over digitalcommunication channels. Through itsPCM interface, SieMo provides hardwaresupport for continual transmission andreception of PCM data, thus reducingprocessor overhead for wireless headsetapplications.SieMo offers a bi-directional digital audiointerface that routes directly into thebaseband layer of the on-chip firmware (itdoes not pass through the HCIprotocollayer). Hardware on SieMo allowsthe data to be sent to and received from aSCO connection. Only one SCOconnection can be supported by the PCMinterface at any one time. Any additionalSCO connections must receive andtransmit their data over the HCI protocollayer. The data format is 13-bit linearPCM. SieMo can operate either as amaster (with an output clock of 256kHz) oras a slave (with the input clock varyingbetween 128kHz and 512kHz). When inslave mode and using higher clock ratesSieMo can support Motorola'sSynchronous Serial Interface (SSI)standard that allows multiple bi-directionalaudio channels to be multiplexed onto asingle physical connection.4.1.3 Generic PCM InterfaceFor a generic PCM interface there is onemaster and one slave device. The mastergenerates the clock and synchronisationsignals. The sync signal identifies the startof the sample data and has an 8kHzperiod. There are two types of frame sync:long andshort. In long frame sync modePCM_SYNC going high indicates the first(and most significant) bit of the sample. Itmust remain high for at least two clockcycles, but this can be longer. In shortframe sync MSB start is signalled by syncgoing low (normally it only goes high forone clock cycle).The clock runs at a higher rate than sync:at least 8 x bits_per_sample MHz,although higher rates are common. Thesample resolution is 13 bits/sample,uncompressed. Several MotorolaCODECs allow their output gain to becontrolled via the addition of three extradata bits after the audio data. SieMosupports this feature, effectively raising thebits per sample to 16. Data from both themaster and slave is clocked out on therising clock edge and sampled on thefalling edge. Master mode is the defaultsetting. In master mode SieMo generatesa 256kHz clock signal (PCM_CLK) and the8kHz, long format synchronisation signal(PCM_SYNC). Short frame sync is notsupported. See PCM Timing Diagrams formore information.Slave mode is selected by setting aPersistent Store value. In slave modeSieMo clocks output data on the risingedge of the received clock signal andsamples incoming data on the falling edge.The incoming clock frequency should bebetween 128kHz and 512kHz. (Note that128kHz is 8 x 16 kHz, therefore theabsolute minimum possible frequency forthe 8ksamples/sec and 16bits/sample (13audio data plus three gain data). Theframe sync must be long format. Shortformat is not supported (see SSI Modeand Timing Diagrams in this section formoreinformation).

SieMo-S50037 Technical Description PRELIMINARYPage 20/294.3 4.4 USB Interface4.4.1 Overview 12Mbits/s bit rate BC01 operates as a peripheral USBdevice Two modes, bus powered and self powered Careful product design is required forproduct to remain USB1.1 compliant 4 USB lines are required Minimum voltage on all VCC terminalsis 3.0V for USB operationThe SieMo contains its own full-speed(12Mbits/s) USB interface. To get aproduct USB 1.1 certified, please visitwww.usb.org for further information. Thevoltage on Vcc-IO must be between 3.0and 3.4 V for USB operation. It is possibleto connect the Vcc-IO to the Vreg output ofthe module, which priveds a regulatedvoltage of 3.15V.Although SieMo is capable of meeting theUSB 1.1 specification, Siemens cannotguarantee that an application circuitdesigned around the IC is USB compliant.The choice of application circuit,component choice and PCB layout allaffect USB signal quality and electricalcharacteristics. The information in thisdocument is intended as a guide andshould be read in association with theUSB 1.1 specification, with particularattention being given to Chapter 7.Independent USB qualification must besought before an application is deemedUSB compliant and can bear the USBlogo. Such qualification can be obtainedfrom a USB plugfest or from anindependent USB test house.4.4.2 Disconnect and Resum eSignallingSieMo provides some signalling lines forUSB operation. These functions aredisabled by default but can be activatedvia firmware settings.The USB_DETACH and USB_WAKE_UPterminals provide extra signallingalongside the normal USB data lines. Theyare not part of the USB specification andfull USB functionality can be attainedwithout their use. The Disconnectmessage may be useful on its own, but itis hard to see an application forUSB_RESUME in isolation.USB_DETACH (Disconnect Signalling)USB_DETACH is an input, when assertedhigh, causes SieMo to putUSB_PULL_UP, USB_D- and USB_D+ ina high-impedance state. This detaches thedevice from the bus and is logicallyequivalent to unplugging the module.When USB_DETACH is taken low, SieMowill connect back to USB and awaitenumeration by the USB host.USB_RESUMEUSB_WAKE_UP is an active high outputused only when USB_DETACH is active towake-up the host and allow USBcommunication to recommence. Itreplaces the function of the USB Resumemessage, which cannot be sent whileSieMo is effectively disconnected from thebus.4.4.3 Power ModesSieMo is by default set to be powered fromthe Bus. It can be set to a self poweredDevice by changing firmware settings. Inthis case the USB_ON must be connectedto the Vbus line via a 47k/22k

This section details the considerations required when interfacing to SieMo via thefour dedicated Serial peripheral interface terminals.4.5.2 Instruction CycleBefore SieMo can be addressed, SPI_CSB must be taken low (SPI_CSB = 0). Data onSPI_MOSI is then clocked into the SieMo on the rising edge of the clockline SPI_CLK. Whenreading, SieMo will reply to the master on MISO, the data being valid on the falling edge ofthe SPI_CLK. The master provides the clocking.
SieMo-S50037 Technical Description PRELIMINARYPage 22/294.5.3 Single-Cycle OperationAfter a serial peripheral interface transaction finishes, the master toggles SPI_CLK withSPI_CSB high to initiate a new transaction. SPI_CSB must be high for at least two SPI_CLKcycles.4.5.4 Multi-Slave OperationSieMo should not be connected in a multi-slave arrangement by simple parallel connection ofslave MISO lines. When SieMo is deselected (SPI_CSB = 1), the SPI_MISO line does notfloat. Instead, SieMo outputs 0 if the processor is running or 1 if it is stopped.4.5.5 Writing to SieMoTo write to the SieMo, the 8-bit write command (00000010) is sent first (C[7:0] followed by a16-bit address (A[15:0]). 16 bits of data (D:[15:0]) are sent.Terminal Type Description DeviceTerminal PC ParallelConnectorSPI_CSB CMOS input Serial Peripheral Interface ChipSelectE1 2SPI_CLK CMOS input Serial Peripheral Interface SPIClockE2 9SPI_MOSI CMOS input Serial Peripheral Interface SPIData InputE3 8SPI_MISO CMOS output Serial Peripheral Interface SPIData OutputE4 10GND B3 194.5.6 SPI Timingfigure 20 SPI write operation a
SieMo-S50037 Technical Description PRELIMINARYPage 23/29figure 21 SPI write operation b4.5.7 Reading from SieMoReading is similar to writing, in that an 8-bit read command (00000011) is sent first, followedby the address of the location to be read. The SieMo then outputs the 16-bit contents of thelocation on MISO during bits D[15:0] and a check-word during T[15:0].The check-word iscomposed of {command, address [15:8]}. The check-word may be used to 'sanity-check' aread operation to a memory location. This overcomes the problem encountered with typicalserial peripheral interface slaves, whereby it is impossible to determine whether the datareturned by a read operation is valid data, or the result ofthe slave device not responding.figure 22 SPI read timing afigure 23 SPI read timing b
SieMo-S50037 Technical Description PRELIMINARYPage 24/294.5.8 Auto-Increment Operati onSending a command word and the address of a register every time it is to be read or writtencan be a significant overhead, especially when large amounts of data are to be transferred.SieMo offers increased data transfer efficiency via its auto-increment operation. Duringoperation, SieMo increments the address automatically. Only the data is transmitted orreceived over the serial peripheral interface bus. SieMo keeps the previous command word.figure 24 Example Auto-Increment Operation
