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 22)
1 = multiframe mode (see the timing in Section 22)
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 3
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.
