NOTES:
1) TSYNC in the frame mode (TCR2.3 = 0) and double-wide frame sync is not enabled (TCR2.4 = 0).
2) TSYNC in the frame mode (TCR2.3 = 0) and double-wide frame sync is enabled (TCR2.4 = 1).
3) TSYNC in the multiframe mode (TCR2.3 = 1).
4) ZBTSI mode disabled (TCR2.5 = 0).
5) TLINK data (FDL bits) is sampled during the F-bit time of odd frame and inserted into the outgoing
6) ZBTSI mode is enabled (TCR2.5 = 1).
7) TLINK data (Z bits) is sampled during the F-bit time of frames 1, 5, 9, 13, 17, and 21 and inserted
8) TLINK and TLCLK are not synchronous with TFSYNC.
T1 stream if enabled via TCR1.2.
