Alrightee I have two questions.
First, if I have a 20MHz crystal + capacitors hooked up to a PIC16F877 at the respsctive pins, this would mean that the actual chip runs at 5MHz, right? (meaning that you just divide whatever size your crystal is by four) I know that this works for another PIC I have, it's just not in the 16F877's datasheet (meaning where you would divide the oscillator by four).
Second, the Part number that I have is a PIC16F877-04/P. Does this mean that the fastest that this chip can run is at 4MHz even though in the datasheet it says that it runs at 20MHz?
