CHAPTER 20 8/10-BIT A/D CONVERTER
20.8
Sample Program 1 for the 8/10-bit A/D Converter
(Single Conversion Mode Using EI
2
OS)
This section contains a sample program for A/D conversion in single conversion mode
using EI
2
OS.
■
Sample Program for Single Conversion Mode using EI
2
OS
●
Processing
•
Analog inputs AN1 to AN3 are converted once.
•
The conversion data is sequentially transferred to addresses 200
H
to 205
H
.
•
A resolution of 10 bits is selected.
•
The conversion is activated by software.
Figure 20.8-1 shows a flowchart of the program using EI
2
OS (single conversion mode).
