NAME AND DESCRIPTION
RSMF
RCR1.7
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
RSM
RCR1.6
RSYNC Mode Select.
0 = frame mode (see the timing in Section 18)
1 = multiframe mode (see the timing in Section 18)
RSIO
RCR1.5
RSYNC I/O Select. (Note: this bit must be set to zero when RCR2.1=0).
0 = RSYNC is an output (depends on RCR1.6)
1 = RSYNC is an input (only valid if elastic store enabled)
RCR1.4
Not Assigned. Should be set to zero when written.
RCR1.3
Not Assigned. Should be set to zero when written.
FRC
RCR1.2
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 three
consecutive times
SYNCE
RCR1.1
Sync Enable.
0 = auto resync enabled
1 = auto resync disabled
RESYNC
RCR1.0
Resync. When toggled from low to high, a resync is initiated. Must be
cleared and set again for a subsequent resync.
