Enhanced Serial Audio Interface Timing
8
The word-relative frame sync signal waveform relative to the clock operates in the same manner as the bit-length frame sync
signal waveform, but spreads from one serial clock before first bit clock (same as bit length frame sync signal), until the one
before last bit clock of the first word in frame.

Note: In network mode, output flag transitions can occur at the start of each time slot within the
frame. In normal mode, the output flag state is asserted for the entire frame period.
