Section 34 Serial Sound Interface (SSI)
34.4.2 Non-Compressed Modes
The non-compressed mode is designed to support all serial audio streams which are split into
channels. It can support Philips, Sony and Matsushita modes as well as many more variants on
these modes.
(1) Slave Receiver
This mode allows the SSI module to receive serial data from another device. The clock and word
select signals used for the serial data stream are also supplied from an external device. If these
signals do not conform to the format as specified in the SSI module then operation is not
guaranteed.
(2) Slave Transmitter
This mode allows the SSI module to transmit serial data to another device. The clock and word
select signals used for the serial data stream are also supplied from an external device. If these
signals do not conform to the format as specified in the SSI module then operation is not
guaranteed.
(3) Master Receiver
This mode allows the SSI module to receive serial data from another device. The clock and word
select signals are internally derived from the HAC_BIT_CLK input clock. The format of these
signals is as defined in the SSI module. If the incoming data does not conform to the defined
format then operation is not guaranteed.
(4) Master Transmitter
This mode allows the SSI module to transmit serial data to another device. The clock and word
select signals are internally derived from the HAC_BIT_CLK input clock. The format of these
signals is as defined in the configuration bits in the SSI module.
(5) Configuration Fields - Word Length Related
All configuration bits relating to the word length of SSICR are valid in non-compressed modes.
There are many configurations that the SSI module can support and it is not sensible to show all of
the Serial Data formats in this document. Some of the combinations are shown below for the
popular formats by Philips, Sony, and Matsushita.
