Non-Compressed Modes

The non-compressed modes support all serial audio streams split into channels. It supports the I
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 this 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 this module, operation is not guaranteed.
(3) Slave Transceiver
This mode allows serial data transmission and reception between this module and 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 this module, operation is not guaranteed.
(4) 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 oversampling clock. The format of these signals is defined in the configuration fields of this module. If
the incoming data from another device does not follow the configured format, operation is not guaranteed.
(5) 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 oversampling clock. The format of these signals is defined in the configuration fields of this module.
(6) Master Transceiver
This mode allows serial data transmission and reception between this module and another device. The clock and word
select signals are internally derived from the oversampling clock. The format of these signals is defined in the
configuration fields of this module.
(7) Operation Setting Related to Word Length
All bits related to the SSICR's word length are valid in non-compressed modes. There are many configurations this
module supports, but some of the combinations are shown below for the I
aligned format, and MSB-first and right-aligned format.
