Note:

EP0 interrupts must be assigned to the same interrupt request signal.

• USBINTN0 signal

DMAC start interrupt signal only EP1. See section 16.8, DMA Transfer.

• USBINTN1 signal

DMAC start interrupt signal only EP1. See section 16.8, DMA Transfer.

• USBINTN2 signal

The USBINTN2 signal requests interrupt sources for which the corresponding bits in interrupt

select registers 0 to 2 (ISR0 to ISR2) are cleared to 0. The USBINTN2 is driven low if a

corresponding bit in the interrupt flag register is set to 1.

• USBINTN3 signal

The USBINTN3 signal requests interrupt sources for which the corresponding bits in interrupt

select registers 0 to 2 (ISR0 to ISR2) are cleared to 0. The USBINTN3 is driven low if a

corresponding bit in the interrupt flag register is set to 1.

• RESUME signal

The RESUME signal is a resume interrupt signal for canceling software standby mode. The

RESUME signal is driven low at the transition to the resume state for canceling software

standby mode.
