The processor supports up to two USB 2.0 Ports. These Ports are configurable as host or device or Dual-Role Device (DRD). USBn_ID (identification) functionality is supported using any of the processor GPIO.
Follow the USB VBUS Design Guidelines section of the device-specific data sheet to scale the USB VBUS voltage (supply connected to the USB interface connector).
VBUS (VBUS supply input including Voltage Scaling Resistor Divider / Clamp) input is recommended to be connected when the device is configured in device mode. Connection of VBUS (VBUS supply input including Voltage Scaling Resistor Divider / Clamp) is optional in host mode.
A power switch with OC (over current) output indication is recommended when the USB interface is configured as host for VBUS control. The USB DRVVBUS drives the power switch. It is recommended to connect the OC output to a processor GPIO, when the USB interface is configured as host.
For details related to USB connections and On-The-Go feature support, refer the device-specific TRM.
For more details, refer the High-speed Serial Interfaces section in the Peripherals chapter of the device-specific TRM.
Refer Pin Connectivity Requirements section of the device-specific data sheet for connecting the USB pins when USB0 and USB1 are not used or USB0 or USB1 is not used.
