• VBERRI: VBus Error Interrupt Flag
In host mode, set by hardware when a VBus drop has been detected. This triggers a USB interrupt if VBERRE = 1.
Shall be cleared by software (by setting the VBERRIC bit) to acknowledge the interrupt.
Note that if a VBus problem occurs, then the VBERRI interrupt is generated even if the USB macro does not go to an error
state because of VBUSHWC = 1.
• BCERRI: B-Connection Error Interrupt Flag
In host mode, set by hardware when an error occurs during the B-connection. This triggers a USB interrupt if BCERRE = 1.
Shall be cleared by software (by setting the BCERRIC bit) to acknowledge the interrupt.
• ROLEEXI: Role Exchange Interrupt Flag
Set by hardware when the USB controller has successfully switched its mode because of an HNP negotiation (host to
device or device to host). This triggers a USB interrupt if ROLEEXE = 1.
Shall be cleared by software (by setting the ROLEEXIC bit) to acknowledge the interrupt.
• HNPERRI: HNP Error Interrupt Flag
In device mode, set by hardware when an error has been detected during an HNP negotiation. This triggers a USB interrupt
if HNPERRE = 1.
Shall be cleared by software (by setting the HNPERRIC bit) to acknowledge the interrupt.
• STOI: Suspend Time-Out Interrupt Flag
In host mode, set by hardware when a time-out error (more than 200ms) has been detected after a suspend. This triggers
a USB interrupt if STOE = 1.
Shall be cleared by software (by setting the STOIC bit) to acknowledge the interrupt.
• VBUSRQ: VBus Request
In host mode, set by software (by setting the VBUSRQS bit) to assert the USB_VBOF output pin in order to enable the
VBus power supply generation.
Cleared by software by setting the VBUSRQC bit.
Cleared by hardware when a VBus error occurs when VBUSHWC = 0.
• ID: USB_ID Pin State
Set/cleared by hardware and reflects the state of the USB_ID input pin, even if USBE = 0.
• VBUS: VBus Level
Set/cleared by hardware and reflects the level of the VBus line, even if USBE = 0.
This bit can be used in device mode to monitor the USB bus connection state of the application.
• SPEED: Speed Status
Set by hardware according to the controller speed mode:
Shall only be used in host mode.
