Select the desire reference voltage to be detected by serial data from the MCU.
The input voltage level of IN1~IN4 will be magnified 4 times using selected
reference voltage as a center. This magnified data will be return to the A-D
input port of the MCU. As result, accuracy of the A-D converter of the MCU will
be increased by 2 bit.
