LED Default Definitions
The RTL8211FS(I)(-VS) 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 and 18 (see section 8.5.22, page 53 and 8.5.24, page 54). The functionality of the RTL8211FS(I)(-VS) LEDs is shown in Table 16.

| 3’b110/3’b111: UTP <==> Fiber (Media Conversion) | Link and Active (Transmitting or Receiving) | UTP and Fiber are both 100M Link up | UTP and Fiber are both 1000M Link up |
LED Register Table
The LED pins can be customized from Page 0xd04 Register 16 and 18. To change the LED settings, see note (below) and Table 17 LED Register Table, which summarizes several configuration types (see also Table 18 LED Configuration Table 1, and Table 19 LED Configuration Table 2, page 34). Note: To switch to Page 0xd04, set Register 31 Data=0x0d04 (set page). After LED setting, switch back to the PHY’s IEEE Standard Registers, i.e. Page 0 or Page 0xa42 (Register 31 Data = 0 or 0xa42).

LED Configuration Table 2
| Pin | Common Mode | Media Select | Description |
|---|
| LED0/LED1/LED2 | 0 | 0 | Media Select bit is valid when Common Mode = 1’b0. The corresponding LED indicates the UTP link status according to LED Configuration Table 1. |
| - | 0 | 1 | Media Select bit is valid when Common Mode = 1’b0. The corresponding LED indicates the SERDES link status according to LED Configuration Table 1. |
| - | 1 | X (Don’t Care) | Media Select bit is not valid when Common Mode = 1’b1. The corresponding LED indicates the UTP and SERDES link status according to LED Configuration Table 1. The behavior must be the same on both sides and then the LED would be active. For example, the LED2 turns on only if the UTP and Fiber are both link up at 1000M in the Media Conversion mode. |
