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.
6.8.9.1 Normal Run, Wait and Stop mode performance over the full
operating voltage range
This section provides the operating performance over the full operating voltage for the
device in Normal Run, Wait and Stop modes.
