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 TCR2.3 = 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.
