20.3 Functional Description

The SSI performs serial-to-parallel conversion on data received from a peripheral device. The CPU

accesses data, control, and status information. The transmit and receive paths are buffered with internal

FIFO memories, allowing up to eight 16-bit values to be stored independently in both transmit and receive

modes. The SSI also supports the µDMA interface. The transmit and receive FIFOs can be programmed

as destination/source addresses in the µDMA module. µDMA operation is enabled by setting the

appropriate bit(s) in the SSIDMACTL register.
