This is a question out of curiosity;
There are pic programmers on the market which can operate from USB power. How is this done? The standard USB interface provides 5 volt power alone. If so, where does the 12 or 13 volts come from to allow a flash pic to enter the programming mode?
Also, in reading the programming specs for flash pics F6xx it is stated that programming high voltage is internally generated. How is this posssible, and if so is it also the case for all other flash pics?
Anybody?
