Write the ADC_CR
with START = 1
If the ADC_CDR is not read before further incoming data is converted, the corresponding Over-
run Error (OVREx) flag is set in the Overrun Status Register (ADC_OVER).
Likewise, new data converted when DRDY is high sets the GOVRE bit (General Overrun Error)
in ADC_SR.
The OVREx flag is automatically cleared when ADC_OVER is read, and GOVRE flag is auto-
matically cleared when ADC_SR is read.
