35 / 77 page  RTL8211E/RTL8211EG Datasheet Integrated 10/100/1000M Ethernet Transceiver 27 Track ID: JATR-2265-11 Rev. 1.5 7.13. LED Configuration The RTL8211E-VB(VL)/RTL8211EG-VB 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 extension Page44 Register 28 and Register 26. The functionality of the RTL8211E-VB(VL)/RTL8211EG-VB LEDs is shown in Table 17. Table 17. LED Default Definitions Pin Description LED0 Blinking=Transmitting or Receiving LED1 Low=Link Up (Any speed) High=Link Down (Any speed) LED2 Low=Link Up (Any speed) High=Link Down (Any speed) Blinking=Transmitting or Receiving Note: When in EEE mode, blinking duration is 400ms ON and 2 seconds OFF. The RTL8211E-VB(VL)/RTL8211EG-VB LED pins can be customized from extension Page 44 Register 28 and Register 26. To change the register page, see note (below) and Table 18. There are 16 configuration types (see Table 19, page 28). Note: To switch to extension Page44, set Register 31 Data=0x0007 (set to extension page). Set Register 30 Data=0x002c (extension Page44). After LED setting, switch to PHY`s Page0 (Register 31 Data=0000). Table 18.
