Conversion Results
Write the ADC_CR
with START = 1
When a conversion is completed, the resulting 10-bit digital value is stored in the Channel Data
Register (ADC_CDR) of the current channel and in the ADC Last Converted Data Register
(ADC_LCDR).
The channel EOC bit in the Status Register (ADC_SR) is set and the DRDY is set. In the case of
a connected PDC channel, DRDY rising triggers a data transfer request. In any case, either
EOC and DRDY can trigger an interrupt.
Reading one of the ADC_CDR registers clears the corresponding EOC bit. Reading ADC_LCDR
clears the DRDY bit and the EOC bit corresponding to the last converted channel.
