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 timing diagrams in Section 22.)
1 = multiframe mode (See timing diagrams 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 three 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.
