Figure 2.5: Isolated Digital Input Connection

2.5.3 Interrupt Function of the DI Signals

DI0 and DI1 can be used to generate hardware interrupts. A user can setup 
the configuration of interrupts by programming the interrupt control regis-
ter.
The channels are connected to the interrupt circuitry. Users can disable/
enable interrupt function, select trigger type or latch the port data by set-
ting the Interrupt Control Register of the UNO-3072L(refer to section 
2.5.5 below). When the interrupt request signals occur, then the software 
will service these interrupt requests by ISR (Interrupt Service Routine). 
The multiple interrupt sources provide the card with more capability and 
flexibility.

2.5.4 IRQ Level

The IRQ level is by default set by the system BIOS. IRQ 7 is reserved for 
DI interrupt and counter interrupt.
