RTL8211F(I)/RTL8211FD(I)

Datasheet

Integrated 10/100/1000M Ethernet Transceiver

Track ID: JATR-8275-15 Rev. 1.1

7.14. LED Configuration

7.14.1. Customized LED Function

The RTL8211F(I)/RTL8211FD(I) supports three LED pins, suitable for multiple types of applications that

can directly drive the LEDs. The output of these pins is determined by setting the corresponding bits in

Page 0xd04 Register 16. The functionality of the RTL8211F(I)/RTL8211FD(I) LEDs is shown in Table 15.

LED1

100M Link and Active (Transmitting or Receiving)

LED2

1000M Link and Active (Transmitting or Receiving)

The LED pins can be customized from Page 0xd04 Register 16. To change the register page, see note

(below) and Table 16 LED Register Table. There are 16 configuration types (see Table 17 LED

Configuration Table, page 27).

Note: To switch to Page 0xd04, set Register 31 Data=0x0d04 (set page). After LED setting, switch to PHY`s

Page 0 (Register 31 Data=0x0000).
