Figure 36-6. Transmit Side D4 Timing
NOTES:
1) TSYNC in the frame mode (IOCR1.2 = 0) and double-wide frame sync is not enabled (IOCR1.1 = 0).
2) TSYNC in the frame mode (IOCR1.2 = 0) and double-wide frame sync is enabled (IOCR1.1 = 1).
3) TSYNC in the multiframe mode (IOCR1.2 = 1).
4) TLINK data (Fs-bits) is sampled during the F-bit position of even frames for insertion into the
outgoing T1 stream when enabled via T1TCR1.2.
