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
