Section 28 A/D Converter
28.1 Overview
This LSI includes a 10-bit successive-approximation A/D converter with a selection of up to six
analog input channels.
28.1.1 Features
A/D converter features are listed below.
• 10-bit resolution
• Six input channels
• High-speed conversion
⎯ Conversion time: maximum 15 µs per channel (with 33-MHz peripheral clock)
• Three conversion modes
⎯ Single mode: A/D conversion of one channel
⎯ Multi mode: A/D conversion on one to four channels
⎯ Scan mode: Continuous A/D 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 the end of conversion
⎯ At the end of A/D conversion, an A/D end interrupt (ADI) can be requested.
