The default value of this field is determined by the strapping of the GPO0/RMII pin. Refer
to
Table 5.38 Register 17 - Mode Control/Status (continued)
Section 4.6.3, "MII vs. RMII Configuration," on page 26
Write as 0, ignore on read.
MII Mode: Reflects the mode of the digital interface:
0 – MII interface.
1 – RMII interface
Note:
Write as 0, ignore on read.
PHY Mode of operation. Refer to

details.
PHY Address.
The PHY Address is used for the SMI address and for
the initialization of the Cipher (Scrambler) key. Refer
to
PHYAD[4:0]," on page 55
Alternate Interrupt Mode.
0 = Primary interrupt system enabled (Default).
1 = Alternate interrupt system enabled.
See
Write as 0, ignore on read.
1 = PHY disregards PHY address in SMI access
0 = normal operation;
1 = force 100TX- link active;
Note:
ENERGYON – indicates whether energy is detected
on the line (see
Power-Down," on page
energy is detected within 256ms. Reset to “1” by
hardware reset, unaffected by SW reset.
Write as 0, ignore on read.
