Figure 25. A Recommended Schematic for the XTAL Oscillator Circuitry
Note:
The user also has an option to drive the Oscillator Circuit with a TTL input signal, in lieu of using a crystal oscillator. If this
approach is used, the TTL must be driven into the X1/CLK pin, and the X2 pin must be left floating.
