Hello Champs,


I'd like to use a USBH1_PWR pin to control an PMIC to feed power for USB devices.

I found a register to change the polarity(H1_PWR_POL) in USBOH1_USB_CTRL register, however which register I can use toggle the pin?




001 Select mux mode: ALT1 mux port: GPIO[27] of instance: gpio6.

010 Select mux mode: ALT2 mux port: USBH1_PWR of instance: usboh1.


Best regards,
