CHAPTER 15 8/10-BIT A/D CONVERTER

15.1 Overview

15.1 Overview
The 8/10-bit A/D converter is a 10-bit successive approximation type of 8/10-bit
A/D converter. It can be started by the software and internal clock, with one
input signal selected from multiple analog input pins.
■ A/D Conversion Function
The A/D converter converts analog voltage (input voltage) input through an analog input pin to
an 8-bit or 10-bit digital value.
• The input signal can be selected from multiple analog input pins.
• The conversion speed can be set in a program. (can be selected according to operating
voltage and frequency).
• An interrupt is generated when A/D conversion is completed.
• The completion of conversion can be determined according to the ADI bit in the ADC1
register.
To activate the A/D conversion function, use one of the following methods.
• Activation using the AD bit in the ADC1 register
• Continuous activation using the 8/16-bit composite timer output TO00
