Usb Interrupt Select Register 2 (Uisr2); Usb Interrupt Select Register 3 (Uisr3) - Hitachi H8S/2215 Series Hardware Manual

15.3.36 USB Interrupt Select Register 2 (UISR2)

UISR2 selects the EXIRQ pin to output interrupt request indicated in the interrupt flag register 2
(UIFR2). When a bit in UIER2 corresponding to the UISR2 bit is set to 1, an interrupt request is
output to EXIRQ0. When a bit in UIER2 corresponding to the UISR2 bit is cleared to 0, an
interrupt request is output to EXIRQ1.

15.3.37 USB Interrupt Select Register 3 (UISR3)

UISR3 selects the EXIRQ pin to output interrupt request indicated in the interrupt flag register 3
(UIFR3). When a bit in UIER3 corresponding to the UISR3 bit is set to 1, an interrupt request is
output to EXIRQ0. When a bit in UIER2 corresponding to the UISR3 bit is cleared to 0, an
interrupt request is output to EXIRQ1.
