Note: The LED interface is EEPROM-programmable, 2 bit EEPROM control bit, Address 0B[7:6] at EEPROM, is
1. LED0: 100Mbps(on, drive '0') or 10Mbps(off, drive '1')
2. LED1: link (keeps on when link ok) or activity (blinks with 10Hz when Pegasus II is receiving or transmitting but
3. LED2: full duplex (keeps on when in full duplex mode) or collision (blinks with 20Hz when colliding)
4. All LED pins will be tri-state when using external PHY (offset 81h with bit[4:2] = 001
