It is necessary to connect a bypass capacitor between the VCC pin and VSS pin and a capacitor
between the VCL pin and VSS pin for stable internal step-down power. An example of connection
is shown in figure 25.35.
It is recommended that a bypass capacitor be connected to
the VCC pin. (The values are reference values.)
When connecting, place a bypass capacitor near the pin.

power stabilization
Do not connect Vcc power supply to the VCL pin.
Always connect a capacitor for internal step-down power
stabilization.
Use one or two ceramic multilayer capacitor(s)
(0.1 µF / 0.47 µF: connect in parallel when using two)
and place it (them) near the pin.
