• When the A/D converter is activated by an external trigger
Do not clear the ADST bit by software during A/D conversion. To stop A/D conversion,
disable external triggers and then rewrite the SCANE bit to change modes from scan mode to
single mode. This stops A/D conversion without clearing the ADST bit by software.
However, after rewriting the SCANE bit, it may take up to 1.5-channel A/D conversion time to
stop A/D conversion and set the A/D end flag (ADF) to 1. Moreover, the ADDR value after
A/D conversion is completed should not be used.
For detailed settings, see figure 18.11.
