28.1.7 Usage Note
The method of connecting an external capacitor is shown in figure 28.4. Connect the system
power supply to the VCL pin together with the VCC pins.
Vcc power supply
Bypass
capacitor
10 µF
VCL
0.01 µF
VSS
< Vcc = 2.7 V to 3.6 V >
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.)
