Offset:
Register Name:
Access Type:
Reset Value:
• IDTI: ID Transition Interrupt Flag
Asynchronous interrupt.
Set by hardware when a transition (high to low, low to high) has been detected on the USB_ID input pin. This triggers a
USB interrupt if IDTE = 1.
Shall be cleared by software (by setting the IDTIC bit) to acknowledge the interrupt (USB clock inputs must be enabled
before).
Note that this interrupt is generated even if the clock is frozen by the FRZCLK bit.
• VBUSTI: VBus Transition Interrupt Flag
Asynchronous interrupt.
Set by hardware when a transition (high to low, low to high) has been detected on the VBUS pad. This triggers a USB inter-
rupt if VBUSTE = 1.
Shall be cleared by software (by setting the VBUSTIC bit) to acknowledge the interrupt (USB clock inputs must be enabled
before).
Note that this interrupt is generated even if the clock is frozen by the FRZCLK bit.
• SRPI: SRP Interrupt Flag
Shall only be used in host mode.
Set by hardware when an SRP has been detected. This triggers a USB interrupt if SRPE = 1.
Shall be cleared by software (by setting the SRPIC bit) to acknowledge the interrupt.
