26.4.2
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)
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)
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)
This mode allows the SSI module to receive serial data from another device. The clock and word
select signals are internally derived from the SSI_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)
This mode allows the SSI module to transmit serial data to another device. The clock and word
select signals are internally derived from the SSI_CLK input clock. The format of these signals is
as defined in the configuration bits in the SSI module.
(5)
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.
