    IN the datasheet of N79E844AWG 8 Bit microcontroller ,it is mentioned that it provides 3 options for the sys clock source.
    1)configured by FOSC(CONFIG3.1).
    2)switches the sys clock from crystal,on chip RC oscillator or external clock from XTAL1 pin.

    so which 1 is better to use??
    seeing from cost perspective,to use FOSC is better.??
