5.5.10 Special Control/Status Indications
5.5.11 Interrupt Source Flag
Index (In Decimal): 27 Size: 16-bits
ADDRESS DESCRIPTION MODE DEFAULT
15:11 Reserved: Write as 0. Ignore on read. RW 0
10 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.

0
9-5 Reserved: Write as 0. Ignore on read. RW 0
4 XPOL: Polarity state of the 10Base-T:
0 - Normal polarity
1 - Reversed polarity
RO 0
3:0 Reserved: Read only - Writing to these bits have no effect. RO 1011b
