I understand that USB_OTG_PWR and USB_H1_PWR are the signals which control each VBUS of USB OTG and USB Host1.

These signals are assigned to the following pins.

- USB_OTG_PWR : EIM_D22(ALT4) or KEY_ROW4(ALT2)
- USB_H1_PWR : EIM_D31(ALT6) or GPIO_0(ALT6)
"To control PMIC to supply VBUS voltage"

However, I cannot find the register bit filde for controlling these signals.
Could you teach register bit filde which controls these signals?

Best Regards,

Hi, YUuki

these two signals are just alike normal GPIO, no special register for USB_OTG_PWR and USB_H1_PWR.
