Figure 21-10 TRANSMIT SIDE BOUNDARY TIMING (with elastic store
disabled)
Notes:
1. TSYNC is in the output mode (TCR2.2 = 1)
2. TSYNC is in the input mode (TCR2.2 = 0)
3. TCHBLK is programmed to block channel 2
4. Shown is TLINK/TLCLK in the ESF framing mode
Figure 21-11 TRANSMIT SIDE 1.544 MHz BOUNDARY TIMING (with elastic
store enabled)
Notes:
1. TCHBLK is programmed to block channel 24 (if the TPCSI bit is set, then the signaling data at TSIG will be ignored during
channel 24).
