(2) A/D converter mode register (ADM)
This register sets the conversion time for analog input to be A/D converted, and starts/stops conversion.
ADM can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

For details of FR2 to FR0, LV1, LV0, and A/D conversion, see Table 12-2 A/D Conversion Time
Selection.
The operation of the A/D voltage comparator is controlled by ADCS and ADCE, and it takes 1
operation start to operation stabilization. Therefore, when ADCS is set to 1 after 1
elapsed from the time ADCE is set to 1, the conversion result at that time has priority over the first
conversion result. Otherwise, ignore data of the first conversion.
