Chapter 15 A/D Converter
15-1

Overview

This LSI has an A/D converter with 10 bits resolution. That has a built-in sample hold circuit, and software
can switch channel 0 to 6 (AN0 to AN6) to analog input. As A/D converter is stopped, the power consump-
tion can be reduced by a built-in ladder resistance. A/D converter is activated by 2 factors : a register setup
or an external interrupt.
