Section 25 USB Function Module
25.3.3 USB Interrupt Select Register 0 (USBISR0)
USBISR0 selects the vector numbers of the interrupt requests indicated in USB interrupt flag
register 0 (USBIFR0). If the USB issues an interrupt request to the INTC when the corresponding
bit in USBISR0 is cleared to 0, the interrupt will be USI0 (USB interrupt 0). If the USB issues an
interrupt request to the INTC when the corresponding bit in USBISR0 is set to 1, the interrupt will
be USI1 (USB interrupt 1). If interrupts occur simultaneously, USI0 has priority by default.
USBISR0 is initialized to H'00 by a power-on reset.
