Peripheral operating requirements and behaviors
6.8.8 I2S/SAI Switching Specifications
This section provides the AC timing for the I2S/SAI module in master mode (clocks are
driven) and slave mode (clocks are input). All timing is given for noninverted serial clock
polarity (TCR2[BCP] is 0, RCR2[BCP] is 0) and a noninverted frame sync (TCR4[FSP]
is 0, RCR4[FSP] is 0). If the polarity of the clock and/or the frame sync have been
inverted, all the timing remains valid by inverting the bit clock signal (BCLK) and/or the
frame sync (FS) signal shown in the following figures.
6.8.8.1 Normal Run, Wait and Stop mode performance over the full
This section provides the operating performance over the full operating voltage for the
device in Normal Run, Wait and Stop modes.
