Bit 7 AWD1: Analog watchdog 1 flag
This bit is set by hardware when the converted voltage crosses the values programmed in ADC_TR1
and ADC_HR1 registers. It is cleared by software by programming it to 1.
0: No analog watchdog event occurred (or the flag event was already acknowledged and cleared by
software)
1: Analog watchdog event occurred
Bits 6:5 Reserved, must be kept at reset value.
Bit 4 OVR: ADC overrun
This bit is set by hardware when an overrun occurs, meaning that a new conversion has complete
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 sequence flag
This bit is set by hardware at the end of the conversion of a sequence of channels selected by the
CHSEL bits. It is cleared by software writing 1 to it.
0: Conversion sequence not complete (or the flag event was already acknowledged and cleared by
software)
1: Conversion sequence complete
Bit 2 EOC: End of conversion flag
This bit is set by hardware at the end of each conversion of a channel when a new data result is
available in the ADC_DR register. It is cleared by software writing 1 to it or by reading the ADC_DR
register.
0: Channel conversion not complete (or the flag event was already acknowledged and cleared by
software)
1: Channel conversion complete
Bit 1 EOSMP: End of sampling flag
This bit is set by hardware during the conversion, at the end of the sampling phase.It is cleared by
software by programming it to '1'.
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 (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
