Section 19 A/D Converter (ADC)
This LSI includes a 10-bit successive-approximation A/D converter with a selection of up to four
analog input channels. Figure 19.1 shows the block diagram of the A/D converter.
19.1 Features
A/D converter features are listed below.
• 10-bit resolution
• 4 input channels
• High-speed conversion
 Conversion time: minimum 15 µs per channel (with Pφ = 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.
