KPCI-3160 User’s Manual

Interrupt example scenario

The following example is one possible scenario that may help you to understand and use the 
KPCI-3160 interrupt feature. (This example is simplified, and some details may not apply to 
your specific system or to your requirements.) It illustrates the workings of the interrupts and 
bits 6, 12, 17, and 23 of the interrupt control/status register. (Refer also to 

Section 4

, “

External 

Interrupts

.”) 

1. At some point, computer software sets interrupt-enable bit 12 of the interrupt control/status 

register to logic-high. (The term “software” here refers to the combination of the application 
programming interface (API)/driver—normally, DriverLINX—and the application program. 
To understand how to program interrupt-triggered data acquisition through DriverLINX, 
refer to your DriverLINX documentation.) This status, detected by board firmware, enables 
the board to process data using external interrupts. It changes general-purpose inputs PC6 
and PC7 of port group 3 into external interrupt request and external interrupt enable inputs 
INT_REQ and INT_ENN.

2. At some point, computer software sets latching polarity bit 6 for port group 0 to determine 

whether that data at port group 0 latches on the rising or falling edge of INT_REQ. This 
action is repeated for port groups 1, 2, and 3.

3. Prior to sending data, a user circuit sets INT_ENN to logic low. Board firmware detects that 

INT_ENN is low and allows the edges of interrupt signals at INT_REQ to be detected.

4. When data is ready to be transferred and processed, the user circuit sends an external inter-

rupt request signal to INT_REQ.

5. Board firmware detects the rising or falling edge of the INT_REQ signal, depending on 

interrupt polarity settings in the port-group control registers (

Table B-2

).

6. Software sets bit 6 of the interrupt control/status register high or low depending on whether 

the user wants a PCI interrupt to be triggered by the falling or rising edge of INT_REQ.

7. If inputs are configured to latch, board firmware latches these input ports. (See bits 5 and 6 in 

Table B-2

.)

8. The interrupt-received status in board firmware causes interrupt-pending bit 17 of the inter-

rupt control/status register to be set to logic high.

9. The interrupt-received status in board firmware causes a computer CPU interrupt to start, 

stopping execution of the current CPU task.

10. Computer hardware detects an interrupt request signal and transfers control to an interrupt 

service routine (ISR).

11. Computer software starts the ISR, which takes control of the CPU and starts processing the 

KPCI-3160 input data.

12. The ISR proceeds. 

13. Ideally, for a well-planned data acquisition session, both of the following conditions are met 

while the ISR is in progress and the interrupt-pending bit is set:

•

No new external interrupt requests occur during this time.

•

If the board is set to detect both the rising and falling edges of an interrupt request signal, 
AND the rising edge started the ISR, then the falling edge does not occur during this 
time.

However if either or both of the above conditions are not met while the interrupt-pending bit 
is set, the following occurs: 

a. The rising and/or falling edges of interrupt signals have no effect; these interrupts are 

missed.
