6) No relationship between TCHCLK and TCHBLK and the other signals is implied.
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.
