Function block description
(1).A-D converter input
Since it capable of driving external PNP Tr. base up to 20mA, it
can supply current of
IDD MAX=20mAXQ1h

Select the desire reference voltage to be detected by serial data
from the microcomputer.
The input voltage level of IN1 and IN2 will be magnified 4 times
using selected reference voltage as a canter.
This magnified data will be return to the A-D input port of the
microcomputer.
As result, accuracy of the A-D converter of the microcomputer will
be increased by 2 bit.
