The four MSB of the FSLEN field.
Determines which edge on Frame Sync will generate the SR.TXSYN interrupt.
1: TSHR value is shifted out during the transmission of the Transmit Frame Sync signal.
0: The TX_DATA line is driven with the default value during the Transmit Frame Sync signal.
This field defines the length of the Transmit Frame Sync signal and the number of bits shifted out from the TSHR register if
TFMR.FSDEN is equal to one.
