I'm using a K64 microcontroller with a battery charger, battery and an external regulator. By consequence i don't use the usb regulator VREGIN pin and the VOUT33 pin to supply my circuit (it works very well). However, now i want to use the USB controller to communicate with a computer by USB. I was wondering how can I do to supply voltage to the USB Controller. Can I connect VOUT33 and VDD together to do this? Am i forced to use the USB regulator?
I would appreciate an help
Thanks to you.
