It is possible to refine some OTG timers thanks to the TIMPAGE and TIMVALUE bit-fields, 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 firmware should
unlock write accesses by setting the UNLOCK bit. This is not required for read accesses, except
before accessing TIMPAGE if it has to be written in order to read the TIMVALUE bit-field of
another OTG timer.
The USB connection is detected from the VBUS pad.
plug-in detector.
The control logic of the VBUS pad outputs two signals:
In device mode, the VBUS bit follows the Session_valid comparator output:
•the Session_valid signal is high when the voltage on the VBUS pad is higher than or equal to
•the Va_Vbus_valid signal is high when the voltage on the VBUS pad is higher than or equal to
•it is set when the voltage on the VBUS pad is higher than or equal to 1.4 V;
1.4 V;
4.4 V.
