This section provides information about SAI/I2S.

4.7.1

SAI/I2S switching specifications

This section provides the AC timings for the SAI in master (clocks driven) and slave (clocks input) modes.

All timings are given for non-inverted serial clock polarity (SAI_TCR[TSCKP] = 0, SAI_RCR[RSCKP]

= 0) and non-inverted frame sync (SAI_TCR[TFSI] = 0, SAI_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

(SAI_BCLK) and/or the frame sync (SAI_FS) shown in the figures below.
