Bit 3: CRC-4 Enable (CRC4) (E1 Mode Only)
0 = Do not search for the CRC-4 multiframe word.
1 = Search for the CRC-4 multiframe word.
Bit 2: Transmit Synchronizer Enable (TSEN)
0 = Transmit synchronizer disabled.
1 = Transmit synchronizer enabled.
Bit 1: Sync Enable (SYNCE)
0 = Auto resync enabled.
1 = Auto resync disabled.
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.
