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 11).
1=multiframe mode (see the timing in Section 11).
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.
Not Assigned. Should be set to 0 when written.
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.
