Continuous scan mode (Polling mode)
In this mode, A/D conversion is performed starting from ANI2 up to ANI5 specified by the
ADSCM0L register. The A/D conversion result is saved to the ADA0CRn register corresponding to
each analog input. A/D conversion starts from ANI0 upon trigger detection, an A/D conversion
interrupt (INTAD) is generated when conversion of the specified analog input ends, and A/D
conversion from ANI0 starts again.
