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 13)
1 = multiframe mode (see the timing in Section 13)
RSYNC I/O Select.
0 = RSYNC is an output (depends on RCR1.6)
1 = RSYNC is an input (only valid if elastic store enabled)
(note: this bit must be set to 0 when RCR2.1=0)
Not Assigned. Should be set to 0 when written to.
Not Assigned. Should be set to 0 when written to.
Frame Resync Criteria.
0 = resync if FAS received in error 3 consecutive times
1 = resync if FAS or bit 2 of non-FAS is received in error 3
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.
