Section 18 A/D Converter
This LSI includes a successive-approximation-type 10-bit A/D converter that allows up to eight
analog input channels to be selected.
18.1 Features
• 10-bit resolution
• Input channels: eight analog input channels
• Analog conversion voltage range can be specified using the reference power supply voltage
pin (AVref) as an analog reference voltage.
• Conversion time: 8.06 µs per channel (at 33-MHz operation)
• Two kinds of operating modes
Single mode: Single-channel A/D conversion
Scan mode: Continuous A/D conversion on 1 to 4 channels
• Four data registers
Conversion results are held in a 16-bit data register for each channel
• Sample and hold function
• Three kinds of conversion start
Software, 8-bit timer (TMR) conversion start trigger, or external trigger signal.
• Interrupt request
A/D conversion end interrupt (ADI) request can be generated
• Module stop mode can be set
