∼ 2 are always read as “0”.

Bit 0 is the AD conversion result store flag <ADRxRF>. When AD conversion result is stored, the flag is set to “1”.

When Lower register (ADRECxL) is read, this bit is cleared to “0”.

Bit 1 is the Overrun flag <OVRx>. This bit is set to “1” if a next conversion result is written to the ADREGxH/L

before both the ADREGxH and ADREGxL are read. This bit is cleared to “0” by reading Flag.
