Electrical Characteristics
5.11
This section provides the AC timings for the SSI in master (clocks driven) and slave modes (clocks input). All timings are given
for non-inverted serial clock polarity (SSI_TCR[TSCKP] = 0, SSI_RCR[RSCKP] = 0) and a non-inverted frame sync
(SSI_TCR[TFSI] = 0, SSI_RCR[RFSI] = 0). If the polarity of the clock and/or the frame sync have been inverted, all the timings
remain valid by inverting the clock signal (SSI_BCLK) and/or the frame sync (SSI_FS) shown in the figures below.
