    Am referring mazzidi for 8051...it says that one machine cycle lasts 12 oscillator periods...
    hence we divide the frequecy of the crystal by 12...
    understood...but i would like to know what is one oscillator period.
    Where can i get the actual waveform working of an instuction in 8051 ??

    Frequency = 1/Period
    Period = 1/Frequency

    I think. The frequency is known, right?

    It is the frequency of the crystal or external oscillator on pins X1/X2
