Ok i have strayed from PICs for a while now so i forgot how this works heh
I am using a PIC18F14K50 with USB enabled. It has a 12MHz crystal on board. Im using the microchip code for USB and this is the config:
Since i have a 12MHz crystal and PLLEN is on then its 48MHz. The thing that confuses me is...
1. Is the 48Mhz for USB only or ENTIRE PIC?
2. Is the 48Mhz my final clock or is it 1/4 of the 48mhz ?
