Figure 20-5. 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 1.
2) RSYNC is in the output mode (RCR2.3 = 0).
3) RSYNC is in the input mode (RCR2.3 = 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 and occupies the MSB position of
channel 1.
