NOTES:
1) TSYNC in frame mode (IOCR1.2 = 0) and double-wide frame sync is not enabled (IOCR1.3 = 0).
2) TSYNC in frame mode (IOCR1.2 = 0) and double-wide frame sync is enabled (IOCR1.3 = 1).
3) TSYNC in multiframe mode (IOCR1.2 = 1).
4) TLINK data (FDL bits) sampled during the F-bit time of odd frame and inserted into the outgoing T1
5) ZBTSI mode is enabled (T1TCR2.1 = 1).
