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 INTENCLR/INTENSET.EMPTY0=1.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the Data Buffer 0 Empty interrupt flag.
Bit 1 – UNDERRUN1 DAC1 Underrun
This flag is cleared by writing a '1' to it.
This flag is set when a start conversion event (START1) occurred before new data is copied/written to the DAC1 data buffer and will generate an interrupt request if INTENCLR/INTENSET.UNDERRUN1=1.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the DAC1 Underrun interrupt flag.
Bit 0 – UNDERRUN0 DAC0 Underrun
This flag is cleared by writing a '1' to it.
This flag is set when a start conversion event (START0) occurred before new data is copied/written to the DAC) data buffer and will generate an interrupt request if INTENCLR/INTENSET.UNDERRUN0=1.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the DAC0 Underrun interrupt flag.
