Section 13 A/D Converter
13.1 Overview
The H8/3039 Group includes a 10-bit successive-approximations A/D converter with a selection
of up to eight analog input channels.
When the A/D converter is not used, it can be halted independently to conserve power. For details
see section 17.6, Module Standby Function.
13.1.1 Features
A/D converter features are listed below.
• 10-bit resolution
• Eight input channels
• Selectable analog conversion voltage range
The analog voltage conversion range can be programmed by input of an analog reference
voltage at the AV_CC pin.
• High-speed conversion
Conversion time: minimum 7.4 µs per channel (with 18 MHz system clock)
• Two conversion modes
Single mode: A/D conversion of one channel
Scan mode: continuous conversion on one to four channels
• Four 16-bit data registers
A/D conversion results are transferred for storage into data registers corresponding to the
channels.
• Sample-and-hold function
• A/D conversion can be externally triggered
• A/D interrupt requested at end of conversion
At the end of A/D conversion, an A/D end interrupt (ADI) can be requested.
