A/D Converter
14-12
[Notes]
If a falling edge is input to the ADTRG pin before the conversion start trigger selection (ADST1 to 0) is
switched to "external trigger" ("01"), the ADEN flag is set at the same time that the switch is made, and A/D
conversion starts.
Fig. 14-5-7 shows an example of a single conversion. In this case, the ADEN conversion start/execution
flag is set at the same time that ADST1 to 0 are switched, and is reset when A/D conversion is completed.

Example of Conversion by Switching to External Trigger Mode (Single Conversion)
Fig. 14-5-8 shows an example of continuous conversion. The ADEN flag is set at the same time that
ADST1 to 0 are switched, and then A/D conversion starts. In the case of continuous conversion, conversion is
stopped by writing "0" to the ADEN flag.
