Undefined Data
If the CDR is not read before further incoming data is converted, the corresponding Overrun
Error (OVRE) flag is set in the Status Register (SR).
In the same way, new data converted when DRDY is high sets the bit GOVRE (General Overrun
Error) in SR.
The OVRE and GOVRE flags are automatically cleared when SR is read.
Warning: If the corresponding channel is disabled during a conversion or if it is disabled and
then reenabled during a conversion, its associated data and its corresponding EOC and OVRE
flags in SR are unpredictable.
