Memory Map of Bluetooth Global Registers ADDRESS DESCRIPTION 0001 2080h–0001 20C8h Global LLC Configuration 0001 20C9h–0001 20FFh Unused 19.7 Bluetooth Sequencer RAM The sequencer RAM is a 1K memory-mapped section of RAM that contains the sequencer program. This RAM can be read and written by the CPU in the same way as the Static RAM space and can also be read by the sequencer in the Bluetooth LLC. Arbitration between these devices is performed in hardware. 19.8 Bluetooth Shared Data RAM The shared data RAM is a 7K memory-mapped section of RAM that contains the link control data, RF programming look-up table, and the link payload. This RAM can be read and written in the same way as the Static RAM space and can also be read by the sequencer in the Bluetooth LLC. Arbitration between these devices is performed in hardware. Table 19-3 shows the memory map of the Bluetooth LLC shared Data RAM. Table 19-3. Memory Map of Bluetooth Shared RAM ADDRESS DESCRIPTION 0001 2500h–0001 26D9h RF Programming Look-up Table 0001 26DAh–0001 26FFh Unused 0001 2700h–0001 273Fh Link Control 0 0001 2740h–0001 277Fh Link Control 1 0001 2780h–0001 27BFh Link Control 2 0001 27C0h–0001 27FFh Link Control 3 0001 2800h–0001 283Fh Link Control 4 0001 2840h–0001 287Fh Link Control 5 0001 2880h–0001 28BFh Link Control 6 0001 28C0h–0001 28FFh Link Control 7 0001 2900h–0001 36FFh Link Payload 0–6 20 Telematics Codec The telematics codec provides dual input channels for voice recognition, telematics, voice-over-IP (VoIP), and Bluetooth applications, and it provides high-quality stereo output for music playback and voice DAC functions. The ADC has these features: • Two differential or single-ended analog microphone input • Two digital microphone interfaces • Programmable microphone gain and muting • SNR of 70 dB for ADC path • Fixed 125× oversampling rate • 8 kHz to 24 kHz • Selectable choice of high-pass filters The stereo DAC has these features: • >85 dB SNR • Selectable mono and stereo modes 126 Telematics Codec Copyright © 2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links :CP3SP33 |
