This is the part number that identifies the CX28250 device (0111).
This is the version number that identifies the specific version of the CX28250 device.
Version numbers start at 1 for the first version and are incremented for each revision
thereafter.

This is a test function; set to a logic 0.
This is a test function; set to a logic 0.
When written to a logic 1, this bit disables the UTOPIA receiver outputs. (This
must not be confused with the DisCellRcvr bit, which completely stops cell
processing). The UtopDis bit puts the receive side of the UTOPIA outputs (i.e.,
URxData[15:0], URxPrty, URxSOC, URxClav, and UTxClav) in a high impedance
state.
These bits hold the Multi-PHY Device Address.
