Section 18 Serial Sound Interface (SSI)
18.4.3 Operation of SSI_CH0 to SSI_CH5
(1) Bus Format
SSI_CH0 to SSI_CH5 can operate as a transmitter or a receiver and can be configured into many
serial bus formats in either mode.
The bus formats can be one of eight major modes as shown in table 18.8.

(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.
(a) 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.
