Figure:1.5.2 External Oscillator
Connect external capacitors suited for the used oscillator.
The reference value denotes external capacity value based on our matching result.
When crystal oscillator or ceramic oscillator is used, the oscillation frequency is changed
..
depending on the value of capacitor. For external capacity value, please consult the oscillator
manufacturer and perform matching tests enough for determining appropriate values.
