12.3 Registers Used in A/D Converter
(1) A/D converter mode register (ADM)
The A/D converter uses the following six registers.
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 sets this register to 00H.
Notes 1.
A/D converter mode register (ADM)
A/D port configuration register (ADPC)
Analog input channel specification register (ADS)
Port mode register 2 (PM2)
10-bit A/D conversion result register (ADCR)
8-bit A/D conversion result register (ADCRH)
Note Ignore data of the first conversion because it is not guaranteed range.

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 comparator is controlled by ADCS and ADCE, and it takes 1 s from operation
start to operation stabilization. Therefore, when ADCS is set to 1 after 1 s or more has 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.
