2. The maximum input frequency depends on the duty cycle of the external clock signal.
3. The maximum input frequency is 25MHz when using an external crystal with the internal oscillator; providing that internal serial
resistance of the crystal is less than 40 . However, higher frequencies can be applied with an external clock source on pin XTAL1,
but in this case, the input clock signal must reach the defined levels V
