NEMO Firmware Functional Description The Nemo module incorporates the CSR BlueCore 6 ROM chipset and ROM Bluetooth firmware.
NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet CSR BLUETOOTH SOFTWARE STACK NEMO is supplied with the CSR BlueCore 6 ROM chip. CSR’s BlueCOre 6 ROM contains the lower layers of the Bluetooth stack. The stack is Bluetooth v2.1+EDR compliant and runs on the internal RISC microcontroller within BlueCore. The implementation shown below illustrates the internal processor of BlueCore running the Bluetooth stack up to the Host Controller Interface (HCI).
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Key Features of the HCI Stack: Standard Bluetooth Functionality CSR supports the following Bluetooth v2.1 + EDR functionality: • • • • • • Secure simple pairing Sniff subrating Encryption pause resume Packet boundary flags Encryption Extended inquiry response CSR supports the following Bluetooth v2.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World The firmware was written against the Bluetooth v2.0+EDR specification. • • • • • • • • • • • • • • • • • • Bluetooth components: o Baseband (including LC) o LM o HCI Standard UART HCI Transport Layers All standard Bluetooth radio packet types Full Bluetooth data rate, enhanced data rates of 2 and 3Mbps Operation with up to seven active slaves Scatternet v2.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Key Features of the HCI Stack: Extra Functionality The firmware extends the standard Bluetooth functionality with the following features: • • • • • • • Supports BlueCore Serial Protocol (BCSP), a proprietary, reliable alternative to the standard Bluetooth UART Host Transport Provides a set of approximately 50 manufacturer-specific HCI extension commands.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World DIGITAL INTERFACES High Speed UART Interface NEMO uses a standard UART interface for communicating to other serial devices. Four signals from NEMO implement the UART function. The signal operation amplitude can be varied with the external +VBT_IO supply pin. This is useful for different systems that support different digital communication amplitudes such as 3.3V or 1.8V.
NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet Figure 5: UART Host Connection BCSP is used to control and format information that flows between the Bluetooth Host and the NEMO modules. The Bluetooth stack carries a set of parallel information that flows between the two process entities, multiplexing them over the single UART link. Figure 6: BCSP Context An instance of the BCSP stack runs on both the Host and the Host Controller (NEMO).
NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet The top of the BCSP stack presents: • • One bidirectional reliable datagram service One bidirectional unreliable datagram service The BCSP protocol is defined to run on a 3-wire UART connection (TXD, RXD, & GND). However, BCSP can also run on a 5 wire UART connection (TXD, RXD, GND, CTS, RTS) which is common for higher baud rates.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Audio PCM and I2S Interfaces The NEMO module has a Pulse Code Modulation (PCM) audio port and I2S interface. These interfaces are intended to be used for quick transfer of synchronous audio date transmitted or received over Bluetooth SCO audio links for voice applications such as headsets and hands free kits. These signals can also vary in operation amplitude based on the +VBT_IO supply pin.

NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet PCM Long Frame Sync Long Frame Sync is a clocking format that controls data transfer for PCM data words or sample between two devices. The rising edge of BT_PCM_SYNC_P indicates the start of a PCM word in Long Frame Sync. When NEMO is configured as a PCM master, generating BT_PCM_SYNC_P and BT_PCM_CLK_P, the BT_PCM_SYNC_P is 8-bits long.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Short Frame Sync In Short Frame Sync, the falling edge of BT_PCM_SYNC_P indicates the start of the PCM word. BT_PCM_SYNC_P is always one clock cycle long. Figure 11: Short Frame Sync (Shown with 16-bit Sample) Like with Long Frame Sync, NEMO samples BT_PCM_RXD_P on the falling edge of BT_PCM_CLK_P and transmits BT_PCM_TXD_P on the rising edge.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Multi-slot Operation More than one audio Bluetooth SCO connection over the PCM interface is supported using multiple slots as more than one Bluetooth SCO connection can exist simultaneously. Up to three Bluetooth SCO connections can be handled simultaneously and can be carried over any of the first three out of the four slots of the PCM port.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World GCI Interface NEMO is compatible with General Circuit Interface (GCI), a standard synchronous 2B+D ISDN timing interface. The two 64kbps B channels can be accessed when this mode is configured. Figure 13: GCI Interface The start of frame is indicated by the rising edge of BT_PCM_SYNC_P and runs at 8kHz. With NEMO in slave mode, the frequency of BT_PCM_CLK can be up to 4.096MHz. Re-Tek - 1573 support@unigen.com http://www.unigen.
NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World PCM Slots and Sample Formats NEMO can receive and transmit on any selection of the first four slots following each sync pulse. Slot durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample formats. Durations of 16 clocks may be used with 8-bit, 13-bit or 16-bit sample formats. NEMO supports 13-bit linear, 16-bit linear and 8-bit μ-law or A-law sample formats.

NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet Figure 17: PCM slave Timing Short Frame Sync PCM CLK and PCM SYNC Generation NEMO has two methods of generating the PCM CLK and PCM SYNC in master mode: • Generating signals by Direct Digital Synthesis (DDS) from internal 4MHz clock. Using this mode limits BT_PCM_CLK_P to 126, 256 or 512kHz, and BT_PCM_SYNC_P to 8kHz.
NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet The equation below describes the PCM CLK frequency when being generated using the internal 48MHz clock: The frequency of the PCM SYNC relative to the PCM CLK is set using either of the two equations below by setting the value of PCM_SYNC_MULT (see Table 10.4): CNT_RATE, CNT_LIMIT and SYNC_LIMIT are set using PSKEY_PCM_LOW_JITTER_CONFIG.

NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World Digital Audio Interface (I²S) The digital audio interface supports the industry standard formats for I²S, left-justified (LJ) or right-justified (RJ). The interface shares the same pins as the PCM interface, which means each audio bus is mutually exclusive in its usage. Table 7 lists these alternative functions.

NEMO Bluetooth Radio Module Datasheet Solutions for a Real Time World BOOTING NEMO ROM The NEMO module contains the CSR BlueCore 6 ROM device. The firmware is loaded from BlueCore’s internal ROM. The NEMO module is boot-strapped to use the UART interface upon power up. The BCSP communication protocol along with the BCCMD protocol is used over the UART. PIO 4 must be held low in order to boot into BCSP over the UART successfully.
NEMO Bluetooth Radio Module Solutions for a Real Time World Datasheet The BCSP stack is used on the host to send sync messages from the host to the NEMO module. The Sync message packet is a reasonably good data set for the analysis to complete, though at high baud rates several sync messages from the BCSP stack may need to be sent. This AUTOBAUD mechanism must complete before any normal UART traffic is passed to or from the host transport.
