24. Synchronous Serial Controller (SSC)

The PortuxG20 has one SSC interface available, depending on the multiplexing of the pins.

The SSC supports many serial synchronous communication protocols generally used in audio and telecom applications such as I2S, Short Frame Sync, Long Frame Sync, etc.

The SSC has separated receive and transmit channels. Each channel has a data, a clock and a frame synchronization signal (RD, RK, RF, resp. TD, TK, TF). Both a receive and a transmit DMA channel are assigned to each SSC.
