Interrupt

IMPORTANT!
This function is only available for C/C++ and Pascal for DOS.

1) i_APCI1500_SetBoardIntRoutineDos (..)

Syntax:
<Return value> = i_APCI1500_SetBoardIntRoutineDos
Parameters:
- Input:
BYTE
VOID
- Output:
No output has occurred.
Task:
This function must be called up for each xPCI-1500 on which an interrupt
action is to be enabled. It installs an user interrupt function in all boards on
which an interrupt is to be enabled.
First calling (first board):
- the user interrupt routine is installed
- interrupts are enabled.
If you operate several boards xPCI-1500 which have to react to interrupts, call
up the function as often as you operate boards xPCI-1500. The variable
v_FunctionName is only relevant for the first calling.
From the second call of the function (next board):
- interrupts are enabled. The first board can receive IRQ.
Interrupt
The user interrupt routine is called up by the system when an interrupt is
generated.
An interrupt is generated when:
- the counter/timer has run down
- an event is generated
- the watchdog has run down
