Conversion Results
With START=1
Write CR
When a conversion is completed, the resulting 10-bit digital value is stored in the Channel Data
Register (CDR) of the current channel and in the ADC Last Converted Data Register (LCDR).
The channel EOC bit in the Status Register (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 CDR registers clears the corresponding EOC bit. Reading LCDR clears the
DRDY bit and the EOC bit corresponding to the last converted channel.
