The compressed mode is used to transfer a continuous bit stream. This would typically be a
compressed bit stream which requires downstream decoding.
When burst mode is not enabled, there is no concept of a data word. However in order to receive
and transmit it is necessary to transfer between the serial bus and word formatted memory.
Therefore the word boundary selection is arbitrary during receive/transmit and must be dealt with
by another module. When burst mode is enabled then data bits being transmitted can be identified
by virtue of the fact that the serial clock output is only activated when there is a word to be output
and only the required number of clock pulses necessary to clock out each 32-bit word are
generated. The serial bit clock stops at a low level when SSICR.SCKP = 0, and at a high level
when SSICR.SCKP = 1. Note burst mode is only valid in the context of the SSI module being a
transmitter of data. Burst mode data cannot be received by this module.
Data is transmitted and received in blocks of 32 bits, and the first bit received/transmitted bit is bit
31 when stored in memory.
