8 bits, independently programmable for input or output. All
pins pulled up to +5V via 47K resistors (default). Positions
available for pull down to ground.. Hardware selectable
via solder gap.

PCI INTA# - mapped to IRQn via PCI BIOS at boot-time
Programmable through PLX9080
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.
