Section 22 A/D Converter (ADC)
Section 22 A/D Converter (ADC)
This LSI includes a 10-bit successive-approximation A/D converter allowing selection of up to
eight analog input channels.
22.1 Features
• Resolution: 10 bits
• Input channels: 8
• Minimum conversion time: 3.9 µs per channel
• Operating modes: 3
 Single mode: A/D conversion on one channel
 Multi mode: A/D conversion on one to four channels or on one to eight channels
 Scan mode: Continuous A/D conversion on one to four channels or on one to eight
channels
• Data registers: 8
Conversion results are held in a 16-bit data register for each channel
• Sample-and-hold function
• A/D conversion start methods: 4
 Software
 Conversion start trigger from multi-function timer pulse unit 2 (MTU2)
 Conversion start trigger from the 8-bit timer (TMR)
 External trigger signal
• Interrupt source
An A/D conversion end interrupt (ADI) request can be generated on completion of A/D
conversion.
• Module standby mode can be set
