SYNC CRITERIA
NAME AND DESCRIPTION
RSYNC Multiframe Function. Only used if the RSYNC pin is
programmed in the multiframe mode (RCR1.6 = 1).
0 = RSYNC outputs CAS multiframe boundaries
1 = RSYNC outputs CRC4 multiframe boundaries
RSYNC Mode Select.
0 = frame mode (see the timing in Section 14)
1 = multiframe mode (see the timing in Section 14)
RSYNC I/O Select. (Note: This bit must be set to 0 when
RCR2.1 = 0.)
0 = RSYNC is an output (depends on RCR1.6)
1 = RSYNC is an input (only valid if elastic store enabled)
Not Assigned. Should be set to 0 when written.
Frame Resync Criteria.
0 = resync if FAS received in error three consecutive times
1 =resync if FAS or bit 2 of non-FAS is received in error three
consecutive times
Sync Enable.
0 = auto resync enabled
1 = auto resync disabled
Resync. When toggled from low to high, a resync is initiated.
Must be cleared and set again for a subsequent resync.
