14.6.2 Scan mode operation

In this mode, the analog inputs specified by the ADMn2 register are selected sequentially from the
ANIn0 pin and are A/D converted the specified number of times using the timer event signal as a
trigger.
The result of conversion is stored in the ADCRnm register corresponding to the analog input. When all
the specified analog input signals have been converted, an A/D conversion end interrupt (INTADn)
occurs.
After conversion has finished, the A/D converter waits for a trigger unless the ADCEn bit of the ADMn0
register is cleared to 0. When a timer event occurs again, the converter starts A/D conversion again,
starting from the ANIn0 input.
This mode is most appropriate for applications in which multiple analog inputs are constantly
monitored.
