31.5.1 ADCON0
Note:
- This bit requires the ON bit to be set.
- If cleared by software while a conversion is in progress, the results of the conversion up to this point will be transferred to ADRES and the state machine will be reset, but the ADIF Interrupt Flag bit will not be set; filter and threshold operations will not be performed.
