This is summarized in Table 5-9. 5.17.3 ENHANCED LED MODE Enhanced mode is enabled when the KSZ9031 LED mode bit in the corresponding port’s LED Control Register 1 is cleared. In Enhanced LED mode, each LED can be configured to display different status information that can be selected by setting the corresponding LED Configuration field of the port’s LED Control Register 2. The modes are detailed in Table 5-10. The blink/pulse-stretch and other LED setting can be configured via the LED Behavior register. TABLE 5-8: INDIVIDUAL-LED MODE OPERATION PORTxLED2 PORTxLED1 Definition Inactive Inactive No link Active Inactive Link any speed, no activity Active Blinking Link any speed, TX or RX activity Other States N/A Note: The LEDs are forced off when any of the following occurs: • The Isolate (PHY_ISO) bit in the Basic Control register is set. • The Power Down bit in the Basic Control register is set. • Coma mode is asserted via the COMA_MODE pin.
