USB Interrupt Select Register 1 (USBISR1)
USBISR1 selects the vector numbers of the interrupt requests indicated in USB interrupt flag
register 1 (USBIFR1). If the USB issues an interrupt request to the INTC when the corresponding
bit in USBISR1 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 USBISR1 is set to 1, the interrupt will
be USI1 (USB interrupt 1). If interrupts occur simultaneously, USI0 has priority by default.
USBISR1 is initialized to H
'
07 by a power-on reset.

USB Interrupt Enable Register 0 (USBIER0)
USBIER0 enables the interrupt requests indicated in USB interrupt flag register 0 (USBIFR0).
When an interrupt flag is set while the corresponding bit in USBIER0 is set to 1, an interrupt
request is sent to the CPU. The interrupt vector number is decided by the contents of USB
interrupt select register 0 (USBISR0).
USBIER0 is initialized to H
'
00 by a power-on reset.
