25.7 Usage Note
The method of connecting an external capacitor is shown in figure 25.29.
Connect the system power supply to the VCL pin together with the VCC pins.

Connect the Vcc power supply to the chip's VCL pin in the
same way as the VCC pins.
It is recommended that a bypass capacitor be connected to the
power supply pins. (Values are reference values.)
