Note: This register has an alternate definition for E1 mode. See RCR1.
Bit 7: Sync Time (SYNCT)
Bit 6: Receive B8ZS Enable (RB8ZS)
Bit 5: Receive Frame Mode Select (RFM)
Bit 4: Auto Resync Criteria (ARC)
Bit 3: Sync Criteria (SYNCC)
Bit 2: Receive Japanese CRC-6 Enable (RJC)
Bit 1: Sync Enable (SYNCE)
Bit 0: Resynchronize (RESYNC). When toggled from low to high, a resynchronization of the receive-side framer is
initiated. Must be cleared and set again for a subsequent resync.
0 = Qualify 10 bits.
1 = Qualify 24 bits.
0 = B8ZS disabled.
1 = B8ZS enabled.
0 = ESF framing mode.
1 = D4 framing mode.
0 = Resync on OOF or LOS event.
1 = Resync on OOF only.
In D4 Framing Mode:
0 = Search for Ft pattern, then search for Fs pattern.
1 = Cross couple Ft and Fs pattern.
In ESF Framing Mode:
0 = Search for FPS pattern only.
1 = Search for FPS and verify with CRC-6.
0 = Use ANSI:AT&T:ITU-T CRC-6 calculation (normal operation).
1 = Use Japanese standard JT–G704 CRC-6 calculation.
0 = Auto resync enabled.
1 = Auto resync disabled.
