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
T1 stream if enabled via TCR1.2
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
into the outgoing stream if enabled via TCR1.2
8. TLINK and TLCLK are not synchronous with TFSYNC

Notes:
1. There is a 10 TCLK delay from TSER to TPOS/TNEG.
2. TSYNC is in the output mode (TCR2.2 = 1)
3. TSYNC is in the input mode (TCR2.2 = 0)
4. TCHBLK is programmed to block channel 2
5. Shown is TLINK/TLCLK in the ESF framing mode
