Arbitration of Conversions
Conversion requests activated while the ADC is idle immediately trigger the requested
conversion. If a conversion is requested while another conversion is already in progress,
the operation of the A/D converter depends on the type of conversions involved (either
standard or injected).
Note: A conversion request is activated if the respective control bit (ADST or ADCRQ)

Abort running conversion,
and start requested new
conversion.
Complete running conversion,
start requested conversion after
that.

Bit ADCRQ will be ‘0’ for the second
conversion, however.
