(2) A/D converter mode register (ADM)
R01UH0106EJ0300 Rev.3.00
Oct 01, 2010
This register sets the conversion time for analog input to be A/D converted, and starts/stops conversion.
The ADM register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

For details of the FR2 to FR0, LV1, LV0 bits, and A/D conversion, see Table 13-2 A/D Conversion Time
Selection.
The operation of the A/D voltage comparator is controlled by the ADCS and ADCE bits, and it takes 1
from operation start to operation stabilization. Therefore, when the ADCS bit is set to 1 after 1
has elapsed from the time ADCE bit is set to 1, the conversion result at that time has priority over the first
conversion result. Otherwise, ignore data of the first conversion.
