Note 1: During power down mode, the LED signals are logic high.

Note 2: LEDS1-0’s initial value comes from the EEPROM. If there is no EEPROM, the default value of the

(LEDS1, LEDS0)=(1, 1).

When implementing dual color LEDs and EEPROM at the same time:

Pin31 and Pin37 of the RTL8111E are shared pins. Follow the RTLRTL8111E reference design (version

1.00 or later) to select these 2 pins for a dual-color LED circuit. Otherwise, the RTLRTL8111E EEPROM

may not function.
