25.3.6 Interrupt Select Register 0 (ISR0)
ISR0 selects the interrupt requests to the INTC to be indicated in interrupt flag register 0. When a
bit in ISR0 is cleared to 0, the corresponding interrupt is requested as a USBFI0 interrupt. When a
bit is set to 1, the corresponding interrupt is requested as a USBFI1 interrupt. With the initial
value, each of the interrupt source flags in the interrupt flag register 0 is selected as a USBFI0
interrupt.
