26. Serial Sound Interface (SSI) Module
Section 26 Serial Sound Interface (SSI) Module
This LSI incorporates two channels of serial sound interface (SSI) modules that send or receive
audio data to or from a variety of devices. In addition to the common formats, they support burst
and multi-channel mode.
26.1 Features
The SSI has the following features.
• Number of channels: Two channels
• Operating modes: Compressed mode and non-compressed mode
The compressed mode is used for continuous bit stream transfer
The non-compressed mode supports all serial audio streams divided into channels.
• The SSI module is configured as any of a transmitter or receiver. The serial bus format (refer
to table 26.3) can be used in the compressed and non-compressed mode.
• Asynchronous transfer between the data buffer and the shift register
• Division ratios of the serial bus interface clock can be selected.
• Data transmission/reception can be controlled from the DMAC or SSI interrupt.
