Function
Chip reset
Crystal input for system clock oscillation (A clock pulse can also be input
to the X1 pin.)
Analog voltage inputs for the A/D converter
Analog voltage inputs for the D/A converter
Application of A/D converter reference voltage
Application of D/A converter reference voltage
Positive power supply for the A/D converter
Ground for the A/D converter
Positive power supply of the port part
Positive power supply except for the port part
Ground of the port part
Ground except for the port part
Directly connect to VSS0. (The TEST pin is for the IC test.)
Notes 1. The potential of the VDD0 pin must be equal to that of the VDD1 pin.
2. The potential of the VSS0 pin must be equal to that of the VSS1 pin.
