Ensure that for 5-V/4-V version products, the input pin voltage does not exceed 7.0 V,
and for 3-V version products, all the input voltage except for port A does not exceed 4.3
V.
Notes: 1. Voltage applied to the VCC1 pin. Since both the VCC1 pin and VCL pin are connected
to the VCC power supply on low-power voltage (3-V) products, VCL ratings should not
be exceeded.
2. Power supply voltage pin used for operation within the chip. Do not apply power supply
voltage to the VCL pin on 5-V/4-V products. Be sure to insert an external capacitor
between the VCL pin and GND to regulate the internal voltage.
