5. System Clock and Oscillator
The oscillator generates the basic clock pulses that provide the system clock to supply CPU and on-chip peripherals.
System clock f
5.1. Instruction Cycle Time:

5.3. Capacitor Selection for Oscillator
Notes:
1. Capacitor values are used for design guidance only!
2. These capacitors were tested with the crystals listed above for basic start-up and operation. They are not optimized.
3. Be careful for the stray capacitance on PCB board, the user should test the performance of the oscillator over the expected
Before selecting crystal, the user should consult the crystal manufacturer for appropriate value of external component to get
