A/D conversion
In this mode, the voltage of the analog input pin specified by the ADA0S register is converted into a digital
value only once.
The conversion result is stored in the ADA0CRn register corresponding to the analog input pin. In this mode,
an analog input pin and an ADA0CRn register correspond on a one-to-one basis. When A/D conversion has
been completed once, the INTAD signal is generated. A/D conversion is stopped after it has been completed
(n = 0 to 11).
In this mode, analog input pins are sequentially selected, from the ANI0 pin to the pin specified by the ADA0S
register, and their values are converted into digital values .
Each conversion result is stored in the ADA0CRn register corresponding to the analog input pin. When
conversion of the analog input pin specified by the ADA0S register is complete, the INTAD signal is generated.
A/D conversion is stopped after it has been completed (n = 0 to 11).

Figure 14-6. Example of Timing in One-Shot Select Mode (ADA0S Register = 01H)
The above timing applies to the software trigger mode (ADA0M0.AD0TMD bit = 0) or the high-
speed conversion mode (ADA0M1.ADA0HS1 bit = 1).
