Interrupt Select Register 1 (ISR1)

ISR1 selects the vector numbers of the interrupt requests indicated in interrupt flag register 1
(IFR1). 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.

22.3.6 Interrupt Select Register 2 (ISR2)
ISR2 selects the vector numbers of the interrupt requests indicated in interrupt flag register 2
(IFR2). 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.
