I know this is a dumb question but I'm trying to educate myself all I can about micro controllers via the web. There are a lot of great resources out there but nevertheless I do have a question. When a micro controller such as a PIC16F876 says that it's got an operating speed of 20 MHz clock input, what exactly does that mean? Can it execute 20,000,000 clock cycles per second? Does it mean that it is capable of keeping track of time in increments as small as 50 nanoseconds? Also, does that mean that you need to use a 20MHz crystal across pins OSC1 and OSC2? Reading a lot online but you guys are a bank of knowledge here as well.
Thanks again!
