Hi,
How does this chip configure the relevant functions of LED pins? For example, how to configure the hardware and software for high LED output?

Hello,
The LED functions are configurable via bootstraps by default. The PHY has auto-detection of the polarization so long as the circuitry is correct. Please take a look at 8.5.2 of the DP83822 datasheet for more information.
Sincerely,
Gerome
