Note: * EP0 interrupts must be assigned to the same interrupt request signal.
• USBINTN0 signal
DTC start interrupt signal only EP1. See section 22.8, DTC Transfer.
• USBINTN1 signal
DTC start interrupt signal only EP1. See section 22.8, DTC 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.
