Name:
ADC_ISR
Address:
0x40038030
Access:
Read-only
• EOCx: End of Conversion x
0 = Corresponding analog channel is disabled, or the conversion is not finished. This flag is cleared when reading the correspond-
ing ADC_CDRx registers.

1 = Corresponding analog channel is enabled and conversion is complete.
• EOCAL: End of Calibration Sequence
0 = Calibration sequence is on going, or no calibration sequence has been requested.
1 = Calibration sequence is complete.
• DRDY: Data Ready
0 = No data has been converted since the last read of ADC_LCDR.
1 = At least one data has been converted and is available in ADC_LCDR.
• GOVRE: General Overrun Error
0 = No General Overrun Error occurred since the last read of ADC_ISR.
1 = At least one General Overrun Error has occurred since the last read of ADC_ISR.
• COMPE: Comparison Error
0 = No Comparison Error since the last read of ADC_ISR.
1 = At least one Comparison Error (defined in the ADC_EMR and ADC_CWR registers) has occurred since the last read of
ADC_ISR.
ADC_ISR.
• ENDRX: End of RX Buffer
0 = The Receive Counter Register has not reached 0 since the last write in ADC_RCR or ADC_RNCR.
1 = The Receive Counter Register has reached 0 since the last write in ADC_RCR or ADC_RNCR.
• RXBUFF: RX Buffer Full
0 = ADC_RCR or ADC_RNCR have a value other than 0.
1 = Both ADC_RCR and ADC_RNCR have a value of 0.
