20.3.7
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).
USBIER1 is initialized to H'00 by a power-on reset.
20.3.8
USBIER2 enables the interrupt requests detected by SET_CONFIGURATION in USB interrupt
flag register 2 (USBIFR2). When the USBIFR2/SETC flag is set while the corresponding bit in
USBIER2 is set to 1, a USIHP interrupt request is sent to the CPU.
USBIER2 is initialized to H'00 by a power-on reset.
