Bit 7 – OVERRUN1 Overrun for Filter Channel 1

This flag is set when the DMA is not cleared while the RESULT1 register gets new data.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit will clear the Overrun for Filter Channel 0 flag.

Value Description

Filter 1 Result Ready interrupt is disabled.

Filter 1 Result Ready interrupt is enabled.

Bit 6 – OVERRUN0 Overrun for Filter Channel 0

This flag is set when the DMA is not cleared while the RESULT0 register gets new data.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit will clear the Overrun for Filter Channel 0 flag.

Bit 5 – RESRDY1 Filter Channel 1 Result Ready

This flag is set when the filter is used as standalone (DACCTRL1.FEXT=1) and the filter output is ready.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit will clear the Filter Channel 1 Result Ready flag.

Bit 4 – RESRDY0 Filter Channel 0 Result Ready

This flag is set when the filter is used as standalone (DACCTRL0.FEXT=1) and the filter output is ready.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit will clear the Filter Channel 0 Result Ready flag.

Bit 3 – EMPTY1 Data Buffer 1 Empty

This flag is cleared by writing a '1' to it or by writing new data to DATA1 or DATABUF1.

This flag is set when the data buffer for DAC1 is empty and will generate an interrupt request if

INTENCLR/INTENSET.EMPTY1=1.

Writing a '0' to this bit has no effect.

Writing a '1' to this bit will clear the Data Buffer 1 Empty interrupt flag.

Bit 2 – EMPTY0 Data Buffer 0 Empty

This flag is cleared by writing a '1' to it or by writing new data to DATA0 or DATABUF0.

This flag is set when the data buffer for DAC0 is empty and will generate an interrupt request if
