CHAPTER 19 8/10-BIT A/D CONVERTER
19.7 Example of Program-2 of 8/10-bit A/D Converter (Example
of Starting the EI
This section shows the A/D conversion program started the EI

Example of EI OS Start Program in Continuous Mode
Processing specification
Convert the analog inputs AN3 to AN5 twice to acquire two converted data for each of channels.
The converted data is transferred to addresses 600
Resolution is assumed to be ten bits.
Start up is performed by 16-bit reload timer 0
