Clear to disable the Role Exchange interrupt (ROLEEXI).
• HNPERRE: HNP Error Interrupt Enable
Set to enable the HNP Error interrupt (HNPERRI).
Clear to disable the HNP Error interrupt (HNPERRI).
• STOE: Suspend Time-Out Interrupt Enable
Set to enable the Suspend Time-Out interrupt (STOI).
Clear to disable the Suspend Time-Out interrupt (STOI).
• VBUSHWC: VBus Hardware Control
Set to disable the hardware control over the USB_VBOF output pin.
Clear to enable the hardware control over the USB_VBOF output pin.
If cleared, then the USB macro considers VBus problems and resets the USB_VBOF output pin in that event.
• SRPSEL: SRP Selection
Set to choose VBus pulsing as SRP method.
Clear to choose data line pulsing as SRP method.
• SRPREQ: SRP Request
Set to initiate an SRP when the controller is in device mode.
Cleared by hardware when the controller is initiating an SRP.
• HNPREQ: HNP Request
When the controller is in device mode:
When the controller is in host mode:
• OTGPADE: OTG Pad Enable
Set to enable the OTG pad.
Clear to disable the OTG pad.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1. Disabling the USB controller (by clearing the USBE
bit) does not reset this bit.
• VBUSPO: VBus Polarity
When 0, the USB_VBOF output signal is in its default mode (active high).
When 1, the USB_VBOF output signal is inverted (active low).
To be generic. May be useful to control an external VBus power module.
Note that this bit can be set/cleared even if USBE = 0 or FRZCLK = 1. Disabling the USB controller (by clearing the USBE
bit) does not reset this bit.
32058J–AVR32–04/11
Set to initiate an HNP.
Cleared by hardware when the controller is initiating an HNP.
Set to accept an HNP.
Clear otherwise.
