Features
- a crystal oscillator a divideby-two counter and three low-power operating modes The oscillator circuit is designed to be used with either a parallel resonant fundamental or third-overtone mode crystal network Alternatively the oscillator circuit may be driven from an external clock source Figure 2 shows the various operating modes of the oscillator circuit The crystal or clock frequency chosen must be twice the required processor operating frequency due to the internal divide-by-two counter This.
