Note: Address prepend for Single Channel UL2 may be inserted in HEC/UDF field

instead of prior to the cell

For Any-PHY mode or single-PHY mode, the address prepend field encoding

indicates the virtual PHY ID. The virtual PHY ID contains 2 sections, the lower 7

bits indicates the virtual PHY ID with valid values for 0 to 83, while the upper bits

are user programmable and not used by the device but may be required in a

user’s system for unique device identification when multiple devices exist on a

bus.

For UTOPIA multi-PHY mode, the address prepend is not used.
