NAME AND DESCRIPTION
Receive Code Select. See Section
0 = idle code (7F Hex)
1 = digital milliwatt code (1E/0B/0B/1E/9E/8B/8B/9E Hex)
Receive Side ZBTSI Enable.
0 = ZBTSI disabled
1 = ZBTSI enabled
RSYNC Double-Wide. (Note: This bit must be set to 0 when
RCR2.4 = 1 or when RCR2.3 = 1.)
0 = do not pulse double-wide in signaling frames
1 = do pulse double-wide in signaling frames
RSYNC Mode Select. (A don’t care if RSYNC is programmed
as an input.)
0 = frame mode (see the timing diagrams in Section 16)
1 = multiframe mode (see the timing diagrams in Section 16)
RSYNC I/O Select. (Note: This bit must be set to 0 when
CCR1.2 = 0.)
0 = RSYNC is an output
1 = RSYNC is an input (only valid if elastic store enabled)

0 = 0s in bit 2 of all channels
1 = a 1 in the S-bit position of frame 12
PCVCR Fs-Bit Error Report Enable.
0 = do not report bit errors in Fs-bit position; only Ft bit position
1 = report bit errors in Fs-bit position as well as Ft bit position
Multiframe Out of Sync Count Register Function Select.
