Interrupt; Fig. 8-4: Protection Circuitry For The Outputs - Addi-Data ADDINUM CPCI-1500 Technical Description

Technical description
These error data are available through an interrupt routine.
See API functions:
8.2.3

Interrupt

The board has an interrupt line. An interrupt line of the PCI bus is allocated to the
board through the BIOS.
Possible interrupt sources:
- Event 1 has occurred (input 1-8),
- Event 2 has occurred (input 9-14),
- Counter/Timer 1 has run down
- Counter/Timer 2 has run down
- Counter/Timer 3 has run down
- Watchdog has run down, the outputs are reset,
- Voltage error (the external voltage supply has dropped below 5 V),
- Short-circuit error, overtemperature error.
The interrupt source information are available on the user program through an
interrupt routine
See API functions:
An event indicates a change of status (level):
- on an input (ex. "0" 1")
- or on several inputs if a logic has been defined between the inputs.
Running-down: if the counter changes from 1
