Section 25 USB Function Module
25.3.6 USB Interrupt Enable Register 1 (USBIER1)
USBIER1 enables the interrupt requests indicated in USB interrupt flag register 1 (USBIFR1).
When an interrupt flag is set while the corresponding bit in USBIER1 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 1 (USBISR1).
USBEPDR0I is initialized to H'00 by a power-on reset.
