* USB Pin Configuration:
*
* This board is equipped with three USB connectors: Type-A (CN7), Mini-B

* either the USB host interface or the USB function interface can be used,
* but not both simultaneously when using the CN7 and CN8 connectors.
*
* By default, the Type-A (CN7) and Mini-B (CN8) connectors are enabled.
* Configure the switches as follows:
* - P02_2 - P02_3 (control signals for USB power supply): DSW2[6] = OFF;
* - P02_2 (used for VBUSEN): DSW14[5] = OFF; DSW14[6] = ON
* - P02_3 (used for USB_OVRCUR): DSW14[1] = OFF; DSW14[2] = ON
* - USB_VBUSIN (used for VBUS of CN8): DSW16[1] = OFF; DSW16[2] = ON
* - USB_VBUSEN (used for USB_HF_VBUSEN): DSW16[3] = OFF; DSW16[4] = ON
*
* To enable the Micro-AB (CN9) USB OTG connector, set the following macro
* to 1 and configure the switches as follows:
* - P02_2 - P02_3 (control signals for USB power supply): DSW2[6] = OFF;
* - P02_2 (used for VBUSEN): DSW14[5] = OFF; DSW14[6] = ON
* - P02_3 (used for USB_OVRCUR): DSW14[1] = OFF; DSW14[2] = ON
* - USB_VBUSIN (used for VBUS for OTG): DSW16[1] = ON; DSW16[2] = OFF
* - USB_VBUSEN (used for USB_OTG_VBUSEN): DSW16[3] = ON; DSW16[4] = OFF
* - USB_EXICEN (used for USB OTG EXICEN): DSW14[3] = OFF; DSW14[4] = ON
