23.5.11.1 Setup and Hold Time Requirements on SFRMIN with
SSPRXD
SSPTXD
SFRM
SCLK
In the Microwire mode, the SSP slave samples the first bit of receive data on the rising edge
of SCLKIN after SFRMIN has gone LOW. Masters that drive a free-running SCLKIN must
ensure that the SFRMIN signal has sufficient setup and hold margins with respect to the
rising edge of SCLKIN.
Figure 23-11
rising edge on which the first bit of receive data is to be sampled by the SSP slave, SFRMIN
must have a setup of at least two times the period of SCLKIN on which the SSP operates.
With respect to the SCLKIN rising edge previous to this edge, SFRMIN must have a hold of
at least one SCLKIN period.
