(2) Single scan mode
In this mode, sequential A/D conversion of the selected analog input channels specified with the
SANI3 - SANI0 and ANIS3 - ANIS0 bits of the ADSCM0L register is performed.
The conversion result for the selected analog inputs is saved to the ADA0CRn registers. A/D
conversion starts upon detection of a trigger, the selected analog inputs are operated in sequence,
and A/D conversion interrupt (INTAD) is output upon conversion completion of the final analog
input channel.
