NAME AND DESCRIPTION
Test Mode Select. Set this bit to a 1 to force all outputs
(including I/O pins) either high (TCR2.6 = 1) or low (TCR2.6 =
0).
Test I/O Pins.
0=force all output (and I/O) pins to a logic 0.
1=force all output (and I/O) pins to a logic 1.
Transmit Side ZBTSI Enable.
0=ZBTSI disabled.
1=ZBTSI enabled.
TSYNC Double-Wide.
0=do not pulse double-wide in signaling frames.
1=do pulse double-wide in signaling frames.
(note: this bit must be set to 0 when TCR 2.3 = 1 or when
TCR2.2 = 0).
TSYNC Mode Select.
0=frame mode (see the timing in Section 13).
1=multiframe mode (see the timing in Section 13).
TSYNC I/O Select.
0=TSYNC is an input.
1=TSYNC is an output.
Transmit Side D4 Yellow Alarm Select.
0=0s in bit 2 of all channels.
1=a 1 in the S-bit position of frame 12.
Bit 7 Zero Suppression Enable.
0=no stuffing occurs.
1=Bit 7 forced to a 1 in channels with all 0s.
