Description

Status and Control Register 2

Fields

REFSEL

Voltage Reference Selection

0 (00): Default voltage reference pin pair (VREFH/VREFL).

1 (01): Analog supply pin pair (VDDA/VSSA).

3 (11): Reserved - Selects default voltage reference (VREFH/VREFL) pin pair.

FFULL

Result FIFO full

0 (0): Indicates that ADC result FIFO is not full and next conversion data still can be stored into FIFO.

1 (1): Indicates that ADC result FIFO is full and next conversion will override old data in case of no read action.

FEMPTY

Result FIFO empty

0 (0): Indicates that ADC result FIFO have at least one valid new data.

1 (1): Indicates that ADC result FIFO have no valid new data.

ACFGT

Compare Function Greater Than Enable

0 (0): Compare triggers when input is less than compare level.

1 (1): Compare triggers when input is greater than or equal to compare level.

ACFE

Compare Function Enable

0 (0): Compare function disabled.

1 (1): Compare function enabled.

ADTRG

Conversion Trigger Select

0 (0): Software trigger selected.

1 (1): Hardware trigger selected.

ADACT

Conversion Active

0 (0): Conversion not in progress.

1 (1): Conversion in progress.
