POSITION NAME AND DESCRIPTION

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

RCR1.6

RSYNC Mode Select.

0 = frame mode (see the timing in Section 13)

1 = multiframe mode (see the timing in Section 13)

RCR1.5

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)

RCR1.4 Not Assigned. Should be set to 0 when written to.

RCR1.3 Not Assigned. Should be set to 0 when written to.

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

RCR1.1

Sync Enable.

0 = auto resync enabled

1 = auto resync disabled

RCR1.0

Resync. When toggled from low to high, a resync is initiated.

Must be cleared and set again for a subsequent resync.
