A/D conversion
Continuous select mode (Polling mode)
In this mode, continuous A/D conversion of one analog input specified with the ADSCM0L register
is performed. The conversion result for that analog input is saved to the ADA0CRn register. A/D
conversion starts upon detection of a trigger, an A/D conversion interrupt (INTAD) is output upon
each conversion completion, and A/D conversion is then started again unless CE bit of ADSCM0H
register is set to 0.
