Clock generator
The oscillator circuit is a single-stage inverting amplifier in a Pierce oscillator configuration. The circuitry between OSCIN
and OSCOUT is basically an inverter biased to the transfer point. A crystal must be used as the feedback element to
complete the oscillator circuitry. It is operated in parallel resonance. OSCIN is the high gain amplifier input and OSCOUT
is the output. To drive the device externally OSCIN is driven from an external source and OSCOUT is left open-circuit.
