When implementing customized LEDs:
Configure OCP address DD90h to support your own LED signals. For example, if the value in the OCP
address DD90h is 0CA9h (0000110010101001b), the LED actions are:
• LED 0: On only in 10M mode, with blinking during TX/RX
• LED 1: On only in 100M mode, with blinking during TX/RX
• LED 2: On only in 1000M mode, with blinking during TX/RX

Note: There are two special modes:
LED OFF Mode: Set all bits to 0. All LED pin output become floating (power saving).
Fixed LED Mode: Set Option 1 LED table Mode: LED0=LED1=LED2=1 or 2 (see Table 13).
