VCOOFF_LP: Forces the Receive PLL 10M to lock on the reference clock
at all times:
0 - Receive PLL 10M can lock on reference or line as needed (normal
operation)
1 - Receive PLL 10M is locked on the reference clock.
In this mode 10M data packets cannot be received.
Reserved: Write as 0. Ignore on read.
XPOL: Polarity state of the 10Base-T:
0 - Normal polarity
1 - Reversed polarity
