13.5.3 Operation modes
(1) Select mode
The following two operation modes are available. These operation modes are set by the ADM register.
One input analog signal specified by the ADS register while the ADM.ADMD bit = 0 is converted.
conversion is complete, the result of conversion is stored in the ADCR register.
At the same time, the A/D conversion end interrupt request signal (INTAD) is generated. However, the INTAD
signal may or may not be generated depending on setting of the PFM and PFT registers. For details, refer to
13.5.4 Power fail detection function.
If anything is written to the ADM, ADS, PFM, and PFT registers during conversion, A/D conversion is aborted. In
the software trigger mode, A/D conversion is started from the beginning again. In the hardware trigger mode, the
A/D converter waits for a trigger.
If the trigger is detected during conversion in hardware trigger mode, A/D conversion is aborted and started again
from the beginning.
