Figure 2.5.2 Examples of sub-clock
Figure 2.5.1 Examples of main clock
2.5.1 Example of Oscillator Circuit
Figure 2.5.1 shows some examples of the main clock circuit, one using an oscillator connected to the
circuit, and the other one using an externally derived clock for input. Figure 2.5.2 shows some examples
of sub-clock circuits, one using an oscillator connected to the circuit, and the other one using an externally
derived clock for input. Circuit constants in Figures 2.5.1 and 2.5.2 vary with each oscillator used. Use
the values recommended by the manufacturer of your oscillator.
