32058K AVR32-01/12
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.
Set to initiate an HNP.
Cleared by hardware when the controller is initiating an HNP.
Set to accept an HNP.
Clear otherwise.
