flag The user should identify which mode will be used in his application to
manage the ADC controller events: Polling mode or Interrupt mode. In the Polling
Mode it is advised to use the following functions: - ADC_GetFlagStatus() : to
check if flags events occur. - ADC_ClearFlag() : to clear the flags events. In the
Interrupt Mode it is advised to use the following functions: - ADC_ITConfig() : to
enable or disable the interrupt source. - ADC_GetITStatus() : to check if Interrupt
occurs. - ADC_ClearITPendingBit() : to clear the Interrupt pending Bit
(corresponding Flag).
The ADC provide 11 Interrupts sources and 11 Flags which can be divided into 3 groups:
(#) Flags and Interrupts for ADC regular channels (##)Flags
 ADC_FLAG_RDY: ADC Ready flag
 ADC_FLAG_EOSMP: ADC End of Sampling flag
 ADC_FLAG_EOC: ADC End of Regular Conversion flag.
 ADC_FLAG_EOS: ADC End of Regular sequence of Conversions flag
 ADC_FLAG_OVR: ADC overrun flag
