All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP/RSCKP = 0) and a
non-inverted frame sync (TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have been
inverted, all the timing remains valid by inverting the clock signal STCK/SRCK and/or the frame sync
STFS/SRFS shown in the tables and in the figures.
There are 2 sets of I/O signals for the SSI module. They are from Port C primary function (PC3 – PC8)
and Port B alternate function (PB14 – PB19). When SSI signals are configured as outputs, they can be
viewed both at Port C primary function and Port B alternate function. When SSI signals are configured as
input, the SSI module selects the input based on status of the FMCR register bits in the Clock controller
module (CRM). By default, the input are selected from Port C primary function.
