Does that mean that instructions can be carried out faster with a higher oscillator frequency?
For example:
4MHz Oscillator: Period (clock cycle) = 1/4MHz = 250ns; 1 instruction = 4 clock cycles = 1us
20MHz Oscillator: Period (clock cycle) = 1/20MHz= 50ns; 1 instruction = 4 clock cycles = 200ns
Is this correct? I would greatly appreciate any examples where certain frequencies are required or additional information on oscillators and their function in PIC circuits.
Sorry, yes that looks right to me.
