NAME AND DESCRIPTION
Line Code Violation Count Register Function Select.
0 = do not count excessive 0s
1 = count excessive 0s
Auto Resync Criteria.
0 = Resync on OOF or RCL event
1 = Resync on OOF only
Out Of Frame Select 1.
0 = 2/4 frame bits in error
1 = 2/5 frame bits in error
Out Of Frame Select 2.
0 = follow RCR1.5
1 = 2/6 frame bits in error
Sync Criteria.
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
Sync Time.
0 = qualify 10 bits
1 = qualify 24 bits
Sync Enable.
0 = auto resync enabled
1 = auto resync disabled
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.
