12.4.4 A/D converter operation modes
(1) Select mode

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 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.
If anything is written to ADM, ADM1, or ADS during conversion, A/D conversion is aborted. In this case, A/D
conversion is started again from the beginning, regardless of being in the software trigger mode or timer trigger
mode (hardware trigger mode).
