MII MGMT: COMMAND REGISTER
READ Operation Enable: Low to High transition initiates a Read cycle.
The read data is returned in the MII MGMT Read Data register. In scan
mode, after each read of the Read Data register, another Read cycle is
performed.
SCAN Mode Enable: When 1 and Read operation is enabled, causes the
MII Management to perform Read cycles automatically.

MII MGMT: ADDRESS REGISTER
Register Address: This field represents the 5-bit Register Address field
of MGMT cycles. Up to 32 registers can be accessed. If scanning across
multiple registers in a PHY is enabled, then load the address of the last
PHY to be scanned here.
Reserved
PHY Address: This field represents the 5-bit PHY Address field of
MGMT cycles. Up to 32 PHYs can be addressed. If scanning across
