V
1. Theoretical minimum. The real minimum value depends on the duty cycle of the input clock signal. 32MHz is the maximum input frequency
when using an external crystal oscillator. However, 32MHz can be applied with an external clock source.
2. The input clock signal must reach the defined levels V
