Default
Bit 7: RSYNC Multiframe Skip Control (RSMS) Useful in framing format conversions from D4 to ESF. This
function is not available when the receive-side elastic store is enabled. RSYNC must be set to output multiframe
pulses (TR.IOCR1.5 = 1 and TR.IOCR1.4 = 0).
Bit 6: RSYNC Mode Select 2 (RSMS2)
Bit 5: RSYNC Mode Select 1(RSMS1) 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 reinsertion is
enabled. See the timing diagrams in Section 12.
Bit 4: RSYNC I/O Select (RSIO) (Note: This bit must be set to 0 when TR.ESCR.0 = 0.)
Bit 3: TSYNC Double-Wide (TSDW) (Note: This bit must be set to 0 when TR.IOCR1.2 = 1 or when TR.IOCR1.1
= 0.)
Bit 2: TSYNC Mode Select (TSM) Selects frame or multiframe mode for the TSYNC pin. See the timing diagrams
in Section 12.
Bit 1: TSYNC I/O Select (TSIO)
Bit 0: Output Data Format (ODF)
0 = RSYNC outputs a pulse at every multiframe
1 = RSYNC outputs a pulse at every other multiframe
T1 Mode: RSYNC pin must be programmed in the output frame mode (TR.IOCR1.5 = 0, TR.IOCR1.4 = 0).
0 = do not pulse double-wide in signaling frames
1 = do pulse double-wide in signaling frames
E1 Mode: RSYNC pin must be programmed in the output multiframe mode (TR.IOCR1.5 = 1, TR.IOCR1.4
= 0).
0 = RSYNC outputs CAS multiframe boundaries
1 = RSYNC outputs CRC4 multiframe boundaries
0 = frame mode
1 = multiframe mode
0 = RSYNC is an output
1 = RSYNC is an input (only valid if elastic store enabled)
0 = do not pulse double-wide in signaling frames
1 = do pulse double-wide in signaling frames
0 = frame mode
1 = multiframe mode
0 = TSYNC is an input
1 = TSYNC is an output
0 = bipolar data at TPOSO and TNEGO
1 = NRZ data at TPOSO; TNEGO = 0
