(3) One-shot select mode
(4) One-shot scan mode
A/D
In this mode, the voltage on 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. The A/D conversion operation 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).
