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 14 is drawn
assuming positive polarity bit clock (TCKP=0) and positive frame sync polarity (TFSP=0).
