 Conversion of analog voltages with the reference voltage pin (V
 Minimum conversion time: 13.3 µs per channel (at 20-MHz operation)
 Single mode: Single-channel A/D conversion
 Scan mode:
 Conversion results are held in a 16-bit data register for each channel
 Choice of software or timer conversion start trigger (TPU), or ADTRG pin
 A/D conversion end interrupt (ADI) request can be generated at the end of A/D conversion
 As the initial setting, A/D converter operation is halted. Register access is enabled by
voltage
exiting module stop mode
