It is possible to refine some OTG timers thanks to the Timer Page (TIMPAGE) and Timer Value
(TIMVALUE) fields in USBCON, as shown by
TIMPAGE is used to select the OTG timer to access while TIMVALUE indicates the time-out
value of the selected timer.
TIMPAGE and TIMVALUE can be read or written. Before writing them, the user shall unlock
write accesses by writing a one to the Timer Access Unlock (UNLOCK) bit in USBCON. This is
not required for read accesses, except before accessing TIMPAGE if it has to be written in order
to read the TIMVALUE field of another OTG timer.
The USB connection is detected from the USB_VBUS pad.

The control logic of the USB_VBUS pad outputs two signals:
In device mode, the USBSTA.VBUS bit follows the Session_valid comparator output:
• 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
