Usage Notes

It is necessary to connect a capacitor between the VCL pin and VSS pin for stable internal voltage.
An example of connection is shown in figure 24.27.
External capacitor
for power stabilization
0.1 µF
or 0.47 µF
Do not connect Vcc power supply to the VCL pin.
Always connect a capacitor for power stabilization.
Use a ceramic multilayer capacitor (0.1 µF or 0.47 µF)
and place it near the pin.
