operation), 21.8 µs per channel (at 6-MHz operation)
⎯ Single mode: Single-channel A/D conversion
⎯ Scan mode: Continuous A/D conversion on 1 to 4 channels
⎯ Conversion results are held in a 16-bit data register for each channel
⎯ Software
⎯ Timer (TPU) conversion start trigger
⎯ External trigger signal (ADTRG)
⎯ An A/D conversion end interrupt request (ADI) can be generated
Analog conversion voltage range settable using the reference voltage pin (Vref) as the
reference voltage
