Description
Reserved
These bits are always read as 0. The write value
should always be 0.
MII Management Data-In
Indicates the level of the MDIO pin.
MII Management Data-Out
Outputs the value set to this bit from the MDIO pin,
when the MMD bit is 1.
MII Management Mode
Specifies the data read/write direction with respect to
the MII.
0: Read direction is indicated
1: Write direction is indicated
MII Management Data Clock
Outputs the value set to this bit from the MDC pin
and supplies the MII with the management data
clock. For the method of accessing the MII registers,
see section 18.4.6, Accessing MII Registers.
