24 / 226 page ![]() KSZ9563R DS00002419D-page 24 2017-2018 Microchip Technology Inc. - Set Port N (1-2), PHY Remote Loopback Register = 0x01F0 - Set Port N (1-2), PHY Basic Control Register = 0x3300 4.2 LEDs Each PHY port has two programmable LED output pins, LEDx_0 and LEDx_1, to indicate the PHY link and activity sta- tus. Two different LED modes are available. The LED mode can be changed individually for each PHY port by writing to the PHY Mode bit in the PHY indirect register: MMD 2, address 0, bit 4: •1 = Single-LED Mode •0 = Tri-Color Dual-LED Mode (Default) Each LED output pin can directly drive an LED with a series resistor (typically 220Ω to 470Ω). LED outputs are active- low. 4.2.1 SINGLE-LED MODE In single-LED mode, the LEDx_1 pin indicates the link status while the LEDx_0 pin indicates the activity status, as shown in Table 4-2. 4.2.2 TRI-COLOR DUAL-LED MODE In tri-color dual-LED mode, the link and activity status are indicated by the LEDx_1 pin for 1000BASE-T; by the LEDx_0 pin for 100BASE-TX; and by both LEDx_1 and LEDx_0 pins, working in conjunction, for 10BASE-T. This behavior is summarized in Table 4-3.
