b_BoardHandle,
BYTE
b_InterruptMask

Parameters:
- Input:
BYTE
b_BoardHandle
Handle of board
PA 1500

v_FunctionName
Name of the user interrupt routine
- 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
