ID detection
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.
Figure 26-11 on page 644
Figure 26-11. ID Detection Input Block Diagram
The USB mode (device or host) can be either detected from the USB_ID pin or software
selected by writing to the UIMOD bit, according to the UIDE bit. This allows the USB_ID pin to be
used as a general purpose I/O pin even when the USB interface is enabled.
By default, the USB_ID pin is selected (UIDE is written to one) and the USBB is in device mode
(UBSTA.ID is one), what corresponds to the case where no Mini-A plug is connected, i.e. no
plug or a Mini-B plug is connected and the USB_ID pin is kept high by the internal pull-up resis-
tor from the I/O Controller (which must be enabled if USB_ID is used).
The ID Transition Interrupt (IDTI) bit in USBSTA is set on each transition of the ID bit, i.e. when a
Mini-A plug (host mode) is connected or disconnected. This does not occur when a Mini-B plug
(device mode) is connected or disconnected.
The USBSTA.ID bit is effective whether the USBB is enabled or not.
• 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.
• It is cleared when the voltage on the USB_VBUS pad is lower than 1.4V.
