Notes:
1. There is a 5 TCLK delay from TSER to TPOS and TNEG
2. TSYNC is in the input mode (TCR1.0 = 0)
3. TSYNC is in the output mode (TCR1.0 = 1)
4. TCHBLK is programmed to block channel 2
5. TLINK is programmed to source the Sa4 bits
6. The signaling data at TSIG during channel 1 is normally overwritten in the transmit formatter with
the CAS multiframe alignment nibble (0000)
7. Shown is a non-align frame boundary
