Register
UIFR3
The EXIRQ0 signal requests interrupt sources for which the corresponding bits in interrupt
select registers 0 to 3 (UISR0 to UISR3) are cleared to 0. The EXIRQ0 is driven low if a
corresponding bit in the interrupt flag register is set to 1.
The EXIRQ1 signal requests interrupt sources for which the corresponding bits in interrupt
select registers 0 to 3 (UISR0 to UISR3) are cleared to 0. The EXIRQ1 is driven low if a
corresponding bit in the interrupt flag register is set to 1.
The IRQ6 signal is specific to the suspend/resume interrupt request. The falling edge of the
IRQ6 signal is output at the transition from the suspend state or from the resume state.
2. An EP1 DMA transfer by a USB request is specified by the EP1T1 and EP1T0 bits in
3. An EP2 DMA transfer by a USB request is specified by the EP2T1 and EP2T0 bits in
4. The suspend/resume interrupt request IRQ6 must be specified to be detected at the

UDMAR.
