Access:
• EOCx: End of Conversion x
0 = Corresponding analog channel is disabled, or the conversion is not finished.
1 = Corresponding analog channel is enabled and conversion is complete.
• OVREx: Overrun Error x
0 = No overrun error on the corresponding channel since the last read of ADC12B_SR.
1 = There has been an overrun error on the corresponding channel since the last read of ADC12B_SR.
• DRDY: Data Ready
0 = No data has been converted since the last read of ADC12B_LCDR.
1 = At least one data has been converted and is available in ADC12B_LCDR.
• GOVRE: General Overrun Error
0 = No General Overrun Error occurred since the last read of ADC12B_SR.
1 = At least one General Overrun Error has occurred since the last read of ADC12B_SR.
• ENDRX: End of RX Buffer
0 = The Receive Counter Register has not reached 0 since the last write in ADC12B_RCR or ADC12B_RNCR.
1 = The Receive Counter Register has reached 0 since the last write in ADC12B_RCR or ADC12B_RNCR.
• RXBUFF: RX Buffer Full
0 = ADC12B_RCR or ADC12B_RNCR have a value other than 0.
1 = Both ADC12B_RCR and ADC12B_RNCR have a value of 0.
