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
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
