M65863FP allows it to form oscillation circuit and a frequency quadruplier (PLL) circuit by connecting an
oscillator element, resistor and capacitor on the outside. This enables it to generate the clock required for
the internal operation, though auto-oscillation by using low-frequency external clock.
