NOTE 1: TSYNC IN FRAME MODE (TCR1.1 = 0).
NOTE 2: TSYNC IN MULTIFRAME MODE (TCR1.1 = 1).
NOTE 3: TLINK IS PROGRAMMED TO SOURCE JUST THE SA4 BIT.
NOTE 4: THIS DIAGRAM ASSUMES BOTH THE CAS MF AND THE CRC4 MF BEGIN WITH THE TAF FRAME.
NOTE 5: TLINK AND TLCLK ARE NOT SYNCHRONOUS WITH TSSYNC.

NOTE 1: TSYNC IS IN THE OUTPUT MODE (TCR1.0 = 1).
NOTE 2: TSYNC IS IN THE INPUT MODE (TCR1.0 = 0).
NOTE 3: TCHBLK IS PROGRAMMED TO BLOCK CHANNEL 2.
NOTE 4: TLINK IS PROGRAMMED TO SOURCE THE SA4 BIT.
NOTE 5: THE SIGNALING DATA AT TSIG DURING CHANNEL 1 IS NORMALLY OVERWRITTEN IN THE TRANSMIT
FORMATTER WITH THE CAS MF ALIGNMENT NIBBLE (0000).
NOTE 6: SHOWN IS A TNAF FRAME BOUNDARY.
