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 set of I/O signals for the SSI module. They are from Port C primary function (pad 257 to pad 261) and Port B
alternate function (pad 283 to pad 288). 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 inputs, the SSI module selects the input based on
FMCR register bits in the Clock controller module (CRM). By default, the input are selected from Port C primary function.
