32.2.3 Terminating a Conversion

If a conversion must be terminated before completion, the GO bit can be cleared in software. The ADRESH and ADRESL registers will be updated with the partially complete Analog-to-Digital conversion sample. Incomplete bits will match the last bit converted. In this case, filter and/or threshold occur.
Important: A device Reset forces all registers to their Reset state. Thus, the ADC module is turned off and any pending conversion is terminated.
