DAQ_ACTIVE: Interrupt is generated when a DAQ sequence is active.
DAQ_STOP: Interrupt is generated when A/D Stop Trigger In is
detected.
DAQ_DONE: Interrupt is generated when a DAQ sequence completes.
DAQ_FIFO_1/4_FULL: Interrupt is generated when ADC FIFO is ¼ full.
DAQ_SINGLE: Interrupt is generated after each conversion completes.
DAQ_EOSCAN: Interrupt is generated after the last channel is converted in
multi-channel scans.
DAQ_EOSEQ: Interrupt is generated after each interval delay during
multi-channel scans.
DAC_ACTIVE: Interrupt is generated when DAC waveform circuitry is
active.
DAC_DONE: Interrupt is generated when a DAC sequence completes.
DAC_FIFO_1/4_EMPTY:
Interrupt is generated DAC FIFO is ¼ empty.
DAC_HIGH_CHANNEL:
Interrupt is generated when the DAC high channel output
is updated.
