MII Port Duplex: This pin sets the duplex of the
MII port. Its’ value can be changed at any time (live
value) and can be overridden by disabling the
Auto-Negotiation (VPHY_AN)
Basic Control Register (VPHY_BASIC_CTRL)
the Virtual PHY.
In MAC mode, this signal is typically tied to the
duplex indication from the external PHY.
In PHY mode, this signal is typically tied high or low
as needed.
The polarity of this signal depends upon the
duplex_pol_strap_mii strap. If duplex_pol_strap_mii
is 0, a MII_DULPEX value of 0 indicates full duplex,
and 1 indicates half duplex. If duplex_pol_strap_mii
is 1, a MII_DULPEX value of 1 indicates full duplex,
and 0 indicates half duplex.
In MAC mode, this signal is input from an
external PHY.
In PHY mode, this signal is output to an external
MAC. See
In MAC mode, this is the receiver clock input from
an external PHY.
In PHY mode, this is the receiver clock output to
an external MAC. See
In SMI/MII slave management modes, this signal
is the management data to/from an external
master.
In MII master management modes, this signal is
the management data to/from an external PHY.
In SMI/MII slave management modes, this is the
management clock input from an external master.
In MII master management modes, this is the
management clock output to an external PHY.
