5.3.1 Setup and hold time requirements on CS with respect to SK in Microwire
mode
In the Microwire mode, the SSP slave samples the first bit of receive data on the rising
edge of SK after CS has gone LOW. Masters that drive a free-running SK must ensure
that the CS signal has sufficient setup and hold margins with respect to the rising edge of
SK.
Figure 20–103
rising edge on which the first bit of receive data is to be sampled by the SSP slave, CS
must have a setup of at least two times the period of SK on which the SSP operates. With
respect to the SK rising edge previous to this edge, CS must have a hold of at least one
SK period.
The register offsets from the SSP controller base addresses are shown in the
