Flags Out
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.
Figure 12 is drawn assuming positive polarity bit clock (TCKP=0) and positive frame sync
polarity (TFSP=0).
