ID detection
Figure 32-6. Plug-in Detection Input Block Diagram
The control logic of the USB_VBUS pad outputs two signals:
In device mode, the USBSTA.VBUS bit follows the Session_valid comparator output:
In host mode, the USBSTA.VBUS bit follows a hysteresis based on Session_valid and
Va_Vbus_valid:
The VBUS Transition Interrupt (VBUSTI) bit in USBSTA is set on each transition of the USB-
STA.VBUS bit.
The USBSTA.VBUS bit is operational regardless of whether the USBC is enabled or not.

• The Session_valid signal is high when the voltage on the USB_VBUS pad is higher than or
• The Va_Vbus_valid signal is high when the voltage on the USB_VBUS pad is higher than or
• It is set when the voltage on the USB_VBUS pad is higher than or equal to 1.4V.
• It is cleared when the voltage on the VBUS pad is lower than 1.4V.
• It is set when the voltage on the USB_VBUS pad is higher than or equal to 4.4V.
