Connect the external capacitance to match the oscillator used.
When using the crystal or ceramic oscillator, consult your oscillator manufacturer to decide
the external capacitance value since the oscillation frequency changes depending on the
..
capacitor value.
..
The external low-speed oscillation of other than 32.768 kHz can't be used.
