Receive Operation

As with transmission the reception can be controlled in one of two ways: either DMA or an
interrupt driven.

Figures 26.23 and 26.24 show the flow of operation.

When disabling the SSI module, the SSI clock must be supplied continuously until the module
enters in the idle state, which is indicated by the IIRQ bit.

Note: * SCKD = 0: Clock input through the SSI_SCK pin

SCKD = 1: Clock input through the SSI_CLK pin
