The serial sound interface (SSI) module is a module designed to send or receive audio data
interface with a variety of devices offering Philips format compatibility. It also provides additional
modes for other common formats, as well as support for a burst and multi-channel mode.
26.1
The SSI has the following features.
• Number of channels: One channel
• Operating modes: Compressed mode and non-compressed mode
• The SSI module is configured as any of a transmitter or receiver. The serial bus format can be
• Asynchronous transfer between the 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 interrupt.
Figure 26.1 is a block diagram of the SSI module.
The compressed mode is used for continuous bit stream transfer
The non-compressed mode supports all serial audio streams divided into channels.
used in the compressed and non-compressed mode.
