to prevent the accuracy of AD conversion from degrading. Not only these analog input shared pins, some other
pins may also be affected by noise arising from input/output to and from adjacent pins.

Make sure the analog input pins (AIN0 to AIN7) are used at voltages within VAREF to AVSS. If any voltage
