22.3.4 Interrupt Select Register 0 (ISR0)
ISR0 selects the vector numbers of the interrupt requests indicated in interrupt flag register 0
(IFR0). If the USB issues an interrupt request to the INTC when a bit in ISR0 is cleared to 0, the
interrupt corresponding to the bit will be USBINTN2. If the USB issues an interrupt request to the
INTC when a bit in ISR0 is set to 1, the corresponding interrupt will be USBINTN3.
