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.
