(EXT_PHY_DET)
Pins RXD[3:1] provide internal pull-down resistors to prevent these pins from floating when
unused. RXD0 (pin 75) does not provide an internal pull-down resistor. This pin must be
pulled or driven to a valid state at all times.
The external SMI port is selected when SMI_SEL = 1. When SMI_SEL = 0, MDIO is tri-
stated and MDC is driven low.

Management Data IO: When SMI_SEL = 1,
this pin is the MII SMI serial IO bus pin.
External PHY Detect: This pin also functions
as a strap input, which can be used to indicate
the presence of an external PHY.

Management Data Clock: When SMI_SEL = 1,
this pin is the MII management data clock.
When SMI_SEL=0, this pin is driven low.
