It is said that 8051 has an on-chip oscillator but requires external clock to run it. What may be the internal circuit for on-chip oscillator, how it runs after connecting crystal oscillator? Also what is the purpose of external capacitor with crystal oscillator?
What was the conclusion?? can any1 sum it up for the OP.
PS: I would have done it my-self, but there are many knowledgeable people over here. They can do this very efficiently. :)
