Chapter 15    A/D Converter

Overview

XV - 2

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.

Table 15-1-1 shows the A/D converter functions.
