Interrupts
The DAQ-16 is capable of generating an interrupt from one of four sources:
1. End of conversion signal
2. DMA terminal count
3. Multi-function timer output
4. External interrupt input
The interrupt source is software selected through the DAQ-16 control word register. The
interrupt level is selected using the jumpers J10 and J11 as shown in Figure 2-11.

External Interrupt
The external interrupt is a TTL compatible input from the D-62 connector. An interrupt
request is generated on a high to low transition of this input.
