How to disable the OTG function of RT1062 and use it as device mode only.

Hello,

We want to use USB of MIMXRT1062 as device mode only.

We would like to use OTG1_PWR, OTG1_OC and OTG1_ID as GPIO because we do not use the OTG function.

The questions are

Q1. To disable OTG and enable device mode only, can I just set the CM register in 42.7.33 USB Device Mode (USB_nUSBMODE) to Device Controller?

Q2. Are there any precautions when using

USB_OTG1_PWR (GPIO_AD_B0_02, GPIO_AD_B1_01)

USB_OTG1_OC (GPIO_AD_B0_03, GPIO_AD_B1_03)

USB_OTG1_ID (GPIO_AD_B0_01, GPIO_AD_B1_02)

as GPIO?

Could you tell me what to be aware of when using these pins as GPIO?
