NAME AND DESCRIPTION
Receive Code Select.
0 = idle code (7F Hex)
1 = digital milliwatt code (1E/0B/0B/1E/9E/8B/8B/9E Hex)
Receive Side ZBTSI Support Enable. Allows ZBTSI information to be output on
RLINK pin.
0 = ZBTSI disabled
1 = ZBTSI enabled
RSYNC Double–Wide. (note: this bit must be set to zero 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. Selects frame or multiframe pulse when RSYNC pin is in output
mode. In input mode (elastic store must be enabled) multiframe mode is only useful
when receive signaling re-insertion is enabled. See the timing in Section 21.
0 = frame mode
1 = multiframe mode
RSYNC I/O Select. (note: this bit must be set to zero when CCR1.2 = 0)
0 = RSYNC is an output
1 = RSYNC is an input (only valid if elastic store enabled)
Receive Side D4 Yellow Alarm Select.
0 = zeros in bit 2 of all channels
1 = a one 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.
0 = count errors in the framing bit position
1 = count the number of multiframes out of sync
