Section 18 A/D Converter
18.7.4
When the A/D start bit (ADST) is cleared during A/D conversion by software, A/D conversion
results may be stored incorrectly (ADDR), or when A/D conversion restarts, the interrupt flag may
be misset.
To avoid these events, follow the steps below.
(1)
As the ADST bit is automatically cleared when A/D conversion is completed, do not clear the
ADST bit by software during A/D conversion.
(2)
• When the A/D converter is activated by software

Do not clear the ADST bit by software during A/D conversion. To stop A/D conversion,
rewrite the SCANE bit to change modes from scan mode to single mode. By rewriting the
SCANE bit, the A/D converter is stopped 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 18.10.
