Reserved.
Parity Bit. The incoming Parity Bit is odd parity when 0, even parity when 1.
Reserved. Write 0 for normal operation.
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
will be discarded. The Unassigned/Idle cell counter is incremented for each cell discarded.
Enable UTOPIA PHY address of link 15. A 1 enables the PHY port Address.
Enable UTOPIA PHY address of link 14.A 1 enables the PHY port Address.
