A/D conversion
The select mode and scan mode are provided as the A/D converter operation modes.
One analog input specified by the analog input channel specification register (ADS), while the ADMD bit of the A/D
converter mode register (ADM) is 0, is A/D converted.
When A/D conversion is complete, the conversion result is stored in the A/D conversion result register (ADCR) and
the A/D conversion end interrupt request signal (INTAD) is generated.
After A/D conversion has been completed, A/D conversion is repeated successively, unless the ADCS bit is set to 0.
If anything is written to the ADM or ADS register during conversion, A/D conversion is aborted. In this case, A/D
conversion is started again from the beginning.
