Figure 13-8. Receive Side 1.544MHz Boundary Timing (With Elastic Store Enabled)
NOTES:
1) RSYNC is in the output mode (TR.IOCR1.4 = 0).
2) RSYNC is in the input mode (TR.IOCR1.4 = 1).
3) RCHBLK is programmed to block channel 24.
Figure 13-9. Receive Side 2.048MHz Boundary Timing (With Elastic Store Enabled)
NOTES:
1) RSERO data in channels 1, 5, 9, 13, 17, 21, 25, and 29 are forced to one.
2) RSYNC is in the output mode (TR.IOCR1.4 = 0).
3) RSYNC is in the input mode (TR.IOCR1.4 = 1).
4) RCHBLK is forced to one in the same channels as RSERO (Note 1).
5) The F-bit position is passed through the receive-side elastic store.
