15.3.39 USB Interrupt Select Register 1 (UISR1) (Only in H8S/2215)
UISR1 selects the EXIRQ pin to output interrupt request indicated in the interrupt flag register 1
(UIFR1). When a bit in UIER1 corresponding to the UISR1 bit is cleared to 0, an interrupt request
is output to EXIRQ0. When a bit in UIER1 corresponding to the UISR1 bit is set to 1, an interrupt
request is output to EXIRQ1.
Bit Bit Name Initial Value R/W Description
7, 6 All 0 R Reserved
These bits are always read as 0.
5 EP3iTFS 0 R/W Selects the EP3iTF interrupt
4 EP3iTRS 0 R/W Selects the EP3iTR interrupt
3
0
R
Reserved
This bit is always read as 0.
2 EP2oREADYS 0 R/W Selects the EP2oREADY interrupt
1 EP2iTRS 0 R/W Selects the EP2iTR interrupt
0 EP2iEMPTYS 0 R/W Selects the EP2iEMPTY interrupt
15.3.40 USB Interrupt Select Register 1 (UISR1) (Only in H8S/2215R, H8S/2215T and
H8S/2215C)

(UIFR1). When a bit in UIER1 corresponding to the UISR1 bit is cleared to 0, an interrupt request
is output to EXIRQ0. When a bit in UIER1 corresponding to the UISR1 bit is set to 1, an interrupt
request is output to EXIRQ1.
