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
