Write 0180h to RN12 to set INT_EN and INT_OE_N;
Write 0010h to RN12 to set LK_DWN_EN;
Monitor PWRDWN/MDINT.
When the PWRDWN/MDINT pin asserts low, the user should read the RN11 register to see
if the LK_DWN is set, i.e. which source caused the interrupt.

Link LED: On when 100 M or 10 M link is active. It also blinks at 10 Hz for transmit and
receive.
Speed LED: 100 Mbps(on) or 10 Mbps(off)
Activity LED: Blinks at 20 Hz when there is a half-duplex activity on the media. It is
driven on continuously if full-duplex configuration is detected, or blinks when a collision
is detected.
