This bit is set when the Buffer Full signal from the Peripheral DMA is active.
This bit is cleared when the Buffer Full signal from the Receive Peripheral DMA is inactive.
This bit is set when the End Receive signal from the Peripheral DMA is active.
This bit is cleared when the End Receive signal from the Peripheral DMA is inactive.
This bit is set when a General Overrun Error has occurred.
This bit is cleared when the SR register is read.
1: At least one General Overrun Error has occurred since the last read of the SR register.
0: No General Overrun Error occurred since the last read of the SR register.
This bit is set when a data has been converted and is available in the LCDR register.
This bit is cleared when the LCDR register is read.
0: No data has been converted since the last read of the LCDR register.
1: At least one data has been converted and is available in the LCDR register.
These bits are set when an overrun error on the corresponding channel has occurred (if implemented).
These bits are cleared when the SR register is read.
0: No overrun error on the corresponding channel (if implemented) since the last read of SR.
1: There has been an overrun error on the corresponding channel (if implemented) since the last read of SR.
These bits are set when the corresponding conversion is complete.
These bits are cleared when the corresponding CDR or LCDR registers are read.
0: Corresponding analog channel (if implemented) is disabled, or the conversion is not finished.
1: Corresponding analog channel (if implemented) is enabled and conversion is complete.
