RX23W Group 37. Serial Sound Interface (SSI)
37.3 Operation
37.3.1 Bus Format
This module can operate as a transmitter or a receiver and can be configured into many serial bus formats in either mode.
The bus format can be selected from one of the six modes shown in
Table 37.5.
37.3.2 Non-Compressed Mode
This SSI supports non-compressed mode only. It supports the I
2
S compatible format as well as MSB-first and
left-justified/right-justified.
(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 master clock. The format of these signals is defined in the configuration fields of this module. If the
incoming data 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 master clock. The format of these signals is defined in the configuration fields of this module.
