System Description
5.1.7 High-Speed SSI
The synchronous serial interface module (SSI) is a full-duplex serial port allowing digital signal processors
(DSPs) to communicate with a variety of serial devices, including industry-standard CODECs, other DSPs,
microprocessors, and peripherals. The SSI is typically used to transfer samples in a periodic manner and
consists of a variety of registers that handle port, status, control, transmit and receive, serial clock
generation, and frame synchronization.
5.1.8 Bluetooth Audio Signal Processor
High audio quality is of great importance to the end user. Section 10.9, “Audio,” describes the audio
features.
A dedicated Bluetooth audio signal-processing module (BTASP) has been designed to give users superior
audio performance. The BTASP module handles all filtering, interpolation, as well as encoding/decoding
with a minimum of processor intervention.
The internal voice-processing unit converts raw 16-bit PCM voice data and compressed voice data to
uncompressed voice. Compression modes are A-Law, µ-Law, and CVSD. It performs filtering and accepts
CODEC rates of 8, 16, 32, and 64 kbits/sec.
An external CODEC connected to the synchronous serial interface (SSI) is required for voice processing, if
needed.
5.1.9 Timer
The dual timer module (TMR) is a general purpose module, used for timing control and
application-specific tasks. The TMR can also be configured to perform pulse width modulation (PWM) or
put into a quadrature-count mode if needed. The TMR contains two identical 16-bit counter/timer groups,
each of which supports counting, prescaling, comparing, loading, capturing, and holding options.
5.1.10 General Purpose Input/Output
The MC72000 Bluetooth Baseband Controller supports a maximum of 16 GPIO lines grouped in two
ports. Port B contains 6 lines, Port C contains 10 lines. These ports can be configured as GPIO pins or
dedicated peripheral interface pins.
5.1.11 JTAG Test Interface Controller
The JTIC interface offers full JTAG and boundary scan capabilities for debug and production test
purposes, as well as access to the JTAG interface on the ARM.
