Hi Expert,

I want to double confirm PWRON pin setting.

I want to power on my device when PWRHOLD  pin pull high without press power button .

BOOT1 = VRTC (High, or 1)
BOOT0 = GND (Low, or 0)

Could I set PWRON pin floating?

Thanks

Daniel

    Hi, Daniel,

       PWRON pin has a pull-up control bit PWRONP which is PUADEN_REG bit4; it's 1 by default which means "Pull-up is enabled". if you don't change it to 0, the PWRON pin can be floating. If you want to have a stronger pull-up, you can still use an external resistor to pull it up.
