When MII/RMII 1 is used by MAC 4 in RMII mode; this
pin is output pin RTXD [1:0].
Input upon reset.
The two pins are strapping pin LEDMODE[1:0].
Each port has four LED indicator pins. Each pin has
different indicator meanings, set by the pins,
LEDMODE[1:0].
LEDMODE[1:0]=11: Duplex/Col + Speed + Link/Act +
Link/Act/Spd.
LEDMODE[1:0]=10: Duplex/Col + Speed + Act + Bi-color
Link/Active.
LEDMODE[1:0]=01: TxAct + Speed + RxAct + Link.
LEDMODE[1:0]=00: Col+ Speed+ Link/Act+ Duplex.
All LED statuses are represented as active-low or high
depending on input strapping, except Bi-color Link/Act in
Bi-color LED mode, whose polarity depends on Spd status.
Link/Act/Spd: Link, Activity, and Speed Indicator.
On for link established.
Blinking every 43ms when the corresponding port is
transmitting or receiving at 100Mbps.
Blinking every 120ms when the port is transmitting or
receiving at 10Mbps.
