Usb Interrupt Enable Register 0 (Uier0); Usb Interrupt Enable Register 1 (Uier1) - Hitachi H8S/2215 Series Hardware Manual

15.3.30 USB Interrupt Enable Register 0 (UIER0)

UIER0 enables the interrupt request indicated in the interrupt flag register 0 (UIFR0). When an
interrupt flag is set while the corresponding bit in UIER0 is set to 1, an interrupt is requested by
asserting the corresponding EXIRQ0 or EXIRQ1 pin. Either EXIRQ0 or EXIRQ1 must be
selected by the interrupt select register 0 (UISR0).

15.3.31 USB Interrupt Enable Register 1 (UIER1)

UIER1 enables the interrupt request indicated in the interrupt flag register 1 (UIFR1). When an
interrupt flag is set while the corresponding bit in UIER1 is set to 1, an interrupt is requested by
asserting the corresponding EXIRQ0 or EXIRQ1 pin. Either EXIRQ0 or EXIRQ1 must be
selected by the interrupt select register 1 (UISR1).
