6.8.10 I2S switching specifications
This section provides the AC timings for the I2S in master (clocks driven) and slave
modes (clocks input). All timings are given for non-inverted serial clock polarity
(TCR[TSCKP] = 0, RCR[RSCKP] = 0) and a non-inverted frame sync (TCR[TFSI] = 0,
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 (I2S_BCLK) and/or the frame sync
(I2S_FS) shown in the figures below.
