Hi,

Please tell me the following. The setting is 100BASE-FX.

1. I learned about the internal process until the PHY link is established from power-on .

What is the specific internal process until the PHY link is established from reset release, when the power is already ON and reset is applied?

    Hello,

    The PHY will behave the same way when reset is applied as it does from power on. This pin is an active low reset input that initializes or reinitializes all the internal registers of the PHY. The PHY will behave the same way when reset is applied as it does from power on.

    1. Reads HW Config through strap pins
    2. Checks if signal detect is used or not
    3. Transmit 100BASE-FX signal
    4. Configures receiver to receive 100BASE-FX signal

    Thanks,
