Figure 36-5. Receive Side 2.048MHz Boundary Timing (With Elastic Store
Enabled)
NOTES:
1) RSER data in channels 1, 5, 9, 13, 17, 21, 25, and 29 are forced to one.
2) RSYNC is in the output mode (IOCR1.4 = 0).
3) RSYNC is in the input mode (IOCR1.4 = 1).
4) RCHBLK is forced to one in the same channels as RSER (Note 1).
5) The F-bit position is passed through the receive-side elastic store.
