The bit allocation of the Debug register is given in
current value of signals useful for debugging.
This is an empty register for testing purposes; see
Registers 19h to 2Eh are not implemented. Operating on these addresses will have no
effect on the PHY.
Address 2Fh does not contain register data. Instead it links to the extended register set.
The immediate register set maps to the lower end of the extended register set.
