Hi,
I am interested in knowing the detailed working of VC bit in OTGSC register. I would like to know whether it can provide internal VBUS signal without any additional peripheral circuitry being added to the controller.?
Please respond soon.
Thanks ,
Sooraj.
Hello Sooraj,
For self-powered USB products that only use USB0 and that do not run in OTG mode,USB0_VBUS can be left disconnected as long as the VC bit in the OTGSC register is set.When this bit is set a voltage is applied to the USB0_VBUS pin internally which is theequivalent of connecting the pin to a 5 V VBUS supply. Keeping the USB0_VBUSdisconnected, ensures that OTG VBUS line pulsing does not go towards the cable.
Have a great day,
Sol
