DESCRIPTION

Output Collision LED status indication (Active Low) if ICFG

= 0. If ICFG = 1, output is MINT and collision

indication is lost.

Output Link LED status indication (Active Low). If ICFG =

0, LNKST flashes to indicate activity.

Output Link status change interrupt. Default active low.

Set register 24, bit 12 = 1 for active high interrupt.
