NOTE 1: TSYNCn IN THE OUTPUT MODE (TIOCR.2 = 1).
NOTE 2: TSYNCn IN THE INPUT MODE (TIOCR.2 = 0).
NOTE 3: TCHBLKn IS PROGRAMMED TO BLOCK CHANNEL 2.
NOTE 4: THE SIGNALING DATA AT TSIGn DURING CHANNEL 1 IS NORMALLY OVERWRITTEN IN THE TRANSMIT
FORMATTER WITH THE CAS MF ALIGNMENT NIBBLE (0000).
NOTE 5: SHOWN IS A TNAF FRAME BOUNDARY.
