Usb Interrupt Select Register 0 (Uisr0); Usb Interrupt Select Register 1 (Uisr1) - Hitachi H8S/2215 Series Hardware Manual

15.3.34 USB Interrupt Select Register 0 (UISR0)

UISR0 selects the EXIRQ pin to output interrupt request indicated in the interrupt flag register 0
(UIFR0). When a bit in UIER0 corresponding to the UISR0 bit is set to 1, an interrupt request is
output to EXIRQ0. When a bit in UIER0 corresponding to the UISR0 bit is cleared to 0, an
interrupt request is output to EXIRQ1.

15.3.35 USB Interrupt Select Register 1 (UISR1)

UISR1 selects the EXIRQ pin to output interrupt request indicated in the interrupt flag register 1
(UIFR1). When a bit in UIER0 corresponding to the UISR0 bit is set to 1, an interrupt request is
output to EXIRQ0. When a bit in UIER1 corresponding to the UISR0 bit is cleared to 0, an
interrupt request is output to EXIRQ1.
