15.3.36 USB Interrupt Enable Register 2 (UIER2) (Only in H8S/2215R, H8S/2215T and
H8S/2215C)
UIER2 enables the interrupt request indicated in the interrupt flag register 2 (UIFR2). When an
interrupt flag is set while the corresponding bit in UIER2 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 2 (UISR2).
Bit Bit Name Initial Value R/W Description
7, 6 All 0 R Reserved
These bits are always read as 0.
5 EP5iTRE 0 R/W Enables the EP5iTR interrupt
4 EP5iTSE 0 R/W Enables the EP5iTS interrupt
3
EP4iALL
EMPTYE
0
R/W
Enables EP4iALLEMPTYE interrupt
2 EP4oREADYE 0 R/W Enables the EP4oREADY interrupt
1 EP4iTRE 0 R/W Enables the EP4iTR interrupt
0 EP4iEMPTYE 0 R/W Enables the EP4iEMPTY interrupt
15.3.37 USB Interrupt Enable Register 3 (UIER3)
UIER3 enables the interrupt request indicated in the interrupt flag register 3 (UIFR3). This register
is readable/writable even though in USB module stop mode. When an interrupt flag is set while
the corresponding bit in UIER3 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 3 (UISR3). Note, however, that the SPRSiE bit is an interrupt enable bit specific to the
IRQ6 pin and cannot be selected by UISR3.
