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

[Taka05]

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?
