i_PA1500_SetBoardIntRoutineDos (..)

Syntax:
<Return value> = i_PA1500_SetBoardIntRoutineDos
Parameters:
- Input:
BYTE b_BoardHandle
BYTE b_InterruptNbr
VOID v_FunctionName
- Output:
No output signal has occurred
Task:
This function must be called up for each PA 1500 on which an interrupt
action is to be enabled.
First calling (first board):
the user interrupt routine is installed
-
interrupts are enabled.
-
If you operate several boards PA 1500 which have to react to interrupts, call
up the function as often as you operate boards PA 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 IRQs.
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
