7	6	5	4	3	2	1	0
—	ARC	OOF1	OOF2	SYNCC	SYNCT	SYNCE	RESYNC
0	0	0	0	0	0	0	0

Bit 6: Auto Resync Criteria (ARC)

0 = resync on OOF or RCL event

1 = resync on OOF only

Bits 4- 5: Out-of-Frame Select Bits (OOF2, OOF1)

OOF2	OOF1	Out-Of-Frame Criteria
0	0	2/4 frame bits in error
0	1	2/5 frame bits in error
1	0	2/6 frame bits in error
1	1	2/6 frame bits in error

Bit 3: Sync Criteria (SYNCC)

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 CRC6

Bit 2: Sync Time (SYNCT) 0 = qualify 10 bits 1 = qualify 24 bits

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 receive-side framer is initiated. Must be cleared and set again for a subsequent resync.
