ID Detection
USB_ID
In host mode, the VBUS bit follows an hysteresis based on Session_valid and Va_Vbus_valid:
The VBus Transition interrupt (VBUSTI) is raised on each transition of the VBUS bit.
The VBUS bit is effective whether the USB macro is enabled or not.
Figure 30-12
The USB mode (device or host) can be either detected from the USB_ID pin or software
selected from 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 = 1) and the USB macro is in device mode (ID = 1),
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 resistor from the GPIO con-
troller (which must be enabled if USB_ID is used).
The ID Transition interrupt (IDTI) is raised 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 ID bit is effective whether the USB macro is enabled or not.
•it is cleared when the voltage on the VBUS pad is lower than 1.4 V.
•it is set when the voltage on the VBUS pad is higher than or equal to 4.4 V;
•it is cleared when the voltage on the VBUS pad is lower than 1.4 V.
