This field selects the divider to apply to the selected transmit clock in order to generate a periodic Frame Sync Signal.
If equal to zero, no signal is generated.
If not equal to zero, a signal is generated each 2 x (PERIOD+1) transmit clock periods.
If STTDLY is not zero, a delay of STTDLY clock cycles is inserted between the start event and the actual start of transmission.
When the transmitter is programmed to start synchronously with the receiver, the delay is also applied.
Note: STTDLY must be written carefully, in relation to Transmit Sync Data transmission.
