TRANSMIT SYSTEM SIDE AC TIMING Figure 24-12
Notes:
1. TSER is only sampled on the falling edge of TSYSCLK when the transmit side elastic store is enabled.
2. TCHCLK and TCHBLK are synchronous with TSYSCLK when the transmit side elastic store is enabled.

Notes:
1. TSYNC is in the output mode (TCR2.2 = 1).
2. TSYNC is in the input mode (TCR2.2 = 0).
3. TSER is sampled on the falling edge of TCLK when the transmit side elastic store is disabled.
4. TCHCLK and TCHBLK are synchronous with TCLK when the transmit side elastic store is disabled.
5. TLINK is only sampled during F-bit locations.
6. No relationship between TCHCLK and TCHBLK and the other signals is implied.
