(1)

The SSP can be used as an SSP Primary, or as an SSP Secondary. When used as a Primary, the SSP can be configured to sample DI

with the same internal clock edge used to transmit the next DO, which provides a full cycle rather than a half cycle timing path, allowing

operation at higher SPI clock frequencies.

(2)

The SSP can be configured into four different operational modes/configurations.
