2.8 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.
