Enable UTOPIA PHY address of IMA Group 1. A 1 enables the PHY port Address.
Enable UTOPIA PHY address of IMA Group 0. A 1 enables the PHY port Address.
Unused. Read all 0’s.
Reserved. Write 0 for normal
Parity Bit. The incoming Parity Bit is odd parity when 0, even parity when 1.
Reserved. Write 0 for normal operation.
UTOPIA loopback mode indicator. When set the Tx UTOPIA will accept cells and loop
these back to the Rx UTOPIA interface. The Rx UTOPIA interface will then output these
cells.

Reserved. Write 0 for normal operation
Selects between 16- and 8-bit mode for the Utopia bus. A 0 selects a 16-bit wide bus and
a 1 selects an 8-bit wide bus.
A 1 resets the state of the Input UTOPIA Controller. Write 0 for normal operation.
Reserved. Write 0 for normal operation.
Unassigned Cell Filter. A 1 signifies that the Unassigned
layer will be discarded. The Unassigned/Idle cell counter is incremented for each cell
discarded.
Idle Cell Filter. A 1 signifies that the Idle
discarded. The Unassigned/Idle cell counter is incremented for each cell discarded.
ATM Forum Polynomial. A 1 disables the addition of the ATM Forum Polynomial
calculation on the HEC calculated as per I.432. A 0 means that the coset value is
included in the HEC value.
