The mechanism used to generate the CPU clock is selected during reset by the logic levels on pins
P0.15-13 (P0H.7-5).

21.4.3 - Clock Generation Modes
The Table 34 associates the combinations of these three bits with the respective clock generation mode.

2. The maximum input frequency depends on the duty cycle of the external clock signal.
3. The maximum input frequency is 32MHz when using an external crystal with the internal oscillator; providing that internal serial
resistance of the crystal is less than 40Ω. 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
