Bits 31:5
Reserved, must be kept cleared.
Bit 4 STRT: Regular channel Start flag
This bit is set by hardware when regular channel conversion starts. It is cleared by software.
0: No regular channel conversion started
1: Regular channel conversion has started
Bit 3 JSTRT: Injected channel Start flag
This bit is set by hardware when injected channel group conversion starts. It is cleared by
software.
0: No injected group conversion started
1: Injected group conversion has started
Bit 2 JEOC: Injected channel end of conversion
This bit is set by hardware at the end of all injected group channel conversion. It is cleared by
software.
0: Conversion is not complete
1: Conversion complete
Bit 1 EOC: End of conversion
This bit is set by hardware at the end of a group channel conversion (regular or injected). It is
cleared by software or by reading the ADC_DR.
0: Conversion is not complete
1: Conversion complete
Bit 0 AWD: Analog watchdog flag
This bit is set by hardware when the converted voltage crosses the values programmed in
the ADC_LTR and ADC_HTR registers. It is cleared by software.
0: No Analog watchdog event occurred
1: Analog watchdog event occurred
