This register configures the operation of the ATM side UTOPIA bus and the sample time of PhyUTxClAv for an IMA
group.
28529-DSH-001-K
Footnote:
(1) The Alpha Value is the number of consecutive invalid ICP cells needed for the link to leave the IMA Sync state.
(2) The Beta Value is the number of consecutive errored ICP cells needed for the link to leave the IMA Sync state.
(3) The Gamma Value is the number of consecutive valid ICP cells needed for the link to enter the IMA Sync state.

0 = ATMURxClAv is set active for selected channel during cell transfer
1 = ATMURxClAv is set inactive for selected channel during cell transfer
0 = ATMUTxClAv is forced inactive/active (based on the state of bit 2) during last 4 bytes/words
for selected channel during cell transfer
1 = ATMUTxClAv reflects true cell available status during last 4 bytes/words for selected channel
during cell transfer
0 = ATMUTxClAv is set inactive for selected channel during cell transfer
1 = ATMUTxClAv is set active for selected channel during cell transfer
1 = ATMURxClAv and ATMUTxClAv do not threestate
0 = For an IMA group, sample PhyUTxClAv during an ICP cell to determine SICP rate
1 = For an IMA group, delay sampling PhyUTxClAv until >5 payload byte periods after an ICP
transfer
