Design Dp83869hm as Gigabit  media convertor  ,1 * 1000BT  to 1 1000BTX ,

1. In datasheet  p70, 0x0 = link OK, which is the 1000BT port or 1000BTX port?

2. The light of Gigabit electrical port and optical port is lik / act. Is it necessary to use MCU to configure the light status?

For details, please refer to how to configure it? If MCU is not needed, how to configure LED0 LED1 LED2 PIN  for lighting?

    Hello,

    To answer your questions:

    1. The value "0x0 = link ok" refers to generic link status. This is speed-agnostic. 

    2. Please refer to section 9.5.2 LED Configuration in the datasheet for proper configuration of LEDs. MCU is not necessary, and configuration may vary depending on strap required. 

    Thank you,

    Nikhil
