Analog-to-digital converters (ADC)
Bit 5 JEOC: Injected channel end of conversion flag
This bit is set by hardware at the end of each injected conversion of a channel when a new data is
available in the corresponding ADCx_JDRy register. It is cleared by software writing 1 to it or by
reading the corresponding ADCx_JDRy register
0: Injected channel conversion not complete (or the flag event was already acknowledged and
cleared by software)
1: Injected channel conversion complete
Bit 4 OVR: ADC overrun
This bit is set by hardware when an overrun occurs on a regular channel, meaning that a new
conversion has completed while the EOC flag was already set. It is cleared by software writing 1 to
it.
0: No overrun occurred (or the flag event was already acknowledged and cleared by software)
1: Overrun has occurred
Bit 3 EOS: End of regular sequence flag
This bit is set by hardware at the end of the conversions of a regular sequence of channels. It is
cleared by software writing 1 to it.
0: Regular Conversions sequence not complete (or the flag event was already acknowledged and
cleared by software)
1: Regular Conversions sequence complete
Bit 2 EOC: End of conversion flag
This bit is set by hardware at the end of each regular conversion of a channel when a new data is
available in the ADCx_DR register. It is cleared by software writing 1 to it or by reading the
ADCx_DR register
0: Regular channel conversion not complete (or the flag event was already acknowledged and
cleared by software)
1: Regular channel conversion complete
Bit 1 EOSMP: End of sampling flag
This bit is set by hardware during the conversion of any channel (only for regular channels), at the
end of the sampling phase.
0: not at the end of the sampling phase (or the flag event was already acknowledged and cleared by
software)
1: End of sampling phase reached
Bit 0 ADRDY: ADC ready
This bit is set by hardware after the ADC has been enabled (bit ADEN=1) and when the ADC
reaches a state where it is ready to accept conversion requests.
It is cleared by software writing 1 to it.
0: ADC not yet ready to start conversion (or the flag event was already acknowledged and cleared
by software)
1: ADC is ready to start conversion
