Figure 36-18. Transmit Side Timing

NOTES:

1) TSYNC in frame mode (IOCR1.2 = 0).

2) TSYNC in multiframe mode (IOCR1.2 = 1).

3) TLINK is programmed to source just the Sa4 bit.

4) This diagram assumes both the CAS MF and the CRC-4 MF begin with the TAF frame.

5) TLINK and TLCLK are not synchronous with TSSYNC.
