Bit 3: CRC-4 Enable (CRC4) (E1 Mode Only).
Bit 2: Transmit Synchronizer Enable (TSEN).
Bit 1: Sync Enable (SYNCE).
Bit 0: Resynchronize (RESYNC). When toggled from low to high, a resynchronization of the transmit-side framer
is initiated. Must be cleared and set again for a subsequent resync.
0 = Do not search for the CRC-4 multiframe word
1 = Search for the CRC-4 multiframe word
0 = Transmit synchronizer disabled
1 = Transmit synchronizer enabled
0 = auto resync enabled
1 = auto resync disabled
