Notes:
ADST Bit (A/D Conversion Start Flag)
1. When the on-chip reference voltage is used as analog input, first set the ADEX0 bit to 1 (on-chip reference
2. Do not set in single sweep mode or repeat sweep mode.
3. When the ADSTBY bit is changed from 0 (A/D operation stops) to 1 (A/D operation enabled), wait for one AD
4. To enable the A/D open-circuit detection assist function, select the conversion start state with the ADDDAEL bit

voltage selected) and then set the OCVREFAN bit in the OCVREFCR register to 1 (on-chip reference voltage
and analog input are connected).
When the on-chip reference voltage is not used as analog input, first set the OCVREFAN bit to 0 (on-chip
reference voltage and analog input are cut off) and then set the ADEX0 bit to 0 (extended analog input pin not
selected).

after setting the ADDDAEN bit to 1 (enabled).
The conversion result for an open circuit varies with external circuits. Careful evaluation should be performed
according to the system before using this function.
If the content of the ADCON1 register is rewritten during A/D conversion, the conversion result is undefined.
