Section 13 A/D Converter (ADC)
This LSI includes a successive approximation type 10-bit A/D converter.
13.1 Features
• 10-bit resolution
• Input channels
 8 channels (two independent A/D conversion modules)
• Conversion time: 2.0 µs per channel (preliminary value, operation when Pφ = 25 MHz)
• Three operating modes
 Single mode: Single-channel A/D conversion
 Continuous scan mode: Repetitive A/D conversion on up to four channels
 Single-cycle scan mode: Continuous A/D conversion on up to four channels
• Data registers
 Conversion results are held in a 16-bit data register for each channel
• Sample-and-hold function
• Three methods for conversion start
 Software
 Conversion start trigger from multifunction timer pulse unit 2 (MTU2)
 External trigger signal
• Interrupt request
 An A/D conversion end interrupt request (ADI) can be generated
• Module standby mode can be set
