LED0/
NWAYEN
Ipu/O
LED Output: Programmable LED0 Output
Config. Mode: If copper mode (FXEN=0), latched as Auto-Negotiation Enable
(register 0h, bit 12) during power-up/reset. If fiber mode (FXEN=1), this pin
configuration is always strapped to disable Auto-Negotiation. See Ta b l e 2-2
for details.
