ID detection
Plug-In detection
Moreover, the pad goes to the Idle state if the macro is disabled or if the DETACH bit is written to
one. It returns to the Active state when USBE is written to one and DETACH is written to zero.
The USB connection is detected from the USB_VBUS pad.
architecture of the plug-in detector.
Figure 26-10. 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 an 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 effective whether the USBB 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.
