Hi,

How should pins #27, 28, 29 be terminated when unused?

Thanks.

    Hello Oguri-san,

    On DP83822 pin 27, 28, and 29 are bootstrap pins. Even when they are not used in MAC connections, they will still act as bootstrap pins. Its ok to leave them unconnected because they have internal pull resistors. When these pins are left unconnected, they will bootstrap in their default mode.
