Interrupts
The USB_VBOF and USB_ID pins are multiplexed with GPIO lines and may also be multiplexed
with lines of other peripherals. In order to use them with the USB, the programmer must first pro-
gram the GPIO controller to assign them to their USB peripheral functions. Moreover, if USB_ID
is used, the GPIO controller must be configured to enable the internal pull-up resistor of its pin.
If USB_VBOF or USB_ID is not used by the application, the corresponding pin can be used for
other purposes by the GPIO controller or by other peripherals.
The 48 MHz USB clock is generated by a dedicated generic clock from the power manager.
Before using the USB, the programmer must ensure that the USB generic clock (USB GCLK) is
enabled at 48 MHz in the power manager.
The USB interface has an interrupt line connected to the interrupt controller. In order to handle
USB interrupts, the interrupt controller must be programmed first.
