Figure 37-12. Transmit-Side Timing
Note 1: TSYNC is in the output mode (IOCR1.1 = 1).
Note 2: TSYNC is in the input mode (IOCR1.1 = 0).
Note 3: TSER is sampled on the falling edge of TCLK when the transmit-side elastic store is disabled.
Note 4: TCHCLK and TCHBLK are synchronous with TCLK when the transmit-side elastic store is disabled.
Note 5: In E1 mode, TLINK is only sampled during Sa bit locations as defined in E1TCR2; no relationship between TLCLK/TLINK and TSYNC
is implied.
