Non-Compressed Modes

The non-compressed modes support all serial audio streams split into channels. It supports Philips,

Sony and Matsushita modes as well as many more variants on these modes.

(1)

Slave Receiver

This mode allows the module to receive serial data from another device. The clock and word

select signal used for the serial data stream is also supplied from an external device. If these

signals do not conform to the format specified in the configuration fields of the SSI module,

operation is not guaranteed.

(2)

Slave Transmitter

This mode allows the module to transmit serial data to another device. The clock and word select

signal used for the serial data stream is also supplied from an external device. If these signals do

not conform to the format specified in the configuration fields of the SSI module, operation is not

guaranteed.

(3)

Master Receiver

This mode allows the module to receive serial data from another device. The clock and word

select signals are internally derived from the AUDIO_CLK input clock. The format of these

signals is defined in the configuration fields of the SSI module. If the incoming data does not

follow the configured format, operation is not guaranteed.

(4)

Master Transmitter

This mode allows the module to transmit serial data to another device. The clock and word select

signals are internally derived from the AUDIO_CLK input clock. The format of these signals is

defined in the configuration fields of the SSI module.

(5)

Operating Setting Related to Word Length

All bits related to the SSICR's word length are valid in non-compressed modes. There are many

configurations the SSI module supports, but some of the combinations are shown below for the

popular formats by Philips, Sony, and Matsushita.
