Table 9-3: Interrupt Mask - Addi-Data ADDINUM CPCI-1500 Technical Description

Technical description
The following errors are possible
- overtemperature
- short-circuit
- no voltage is available
If several boards are operated and if they have to react to interrupts, the variable
b_BoardHandle returns the identification number (handle) of the board which
has generated the interrupt.
The user interrupt routine must have the following syntax:
VOID v_FunctionName (BYTE
v_FunctionName
b_BoardHandle
b_InterruptMask
b_InputChannelNbr
The user can give another name for v_FunctionName, b_BoardHandle,
b_InterruptMask, b_InputChannelNbr.

Name of the user interrupt routine
Handle of the xPCI-1500 which has generated the
interrupt
Mask of the events which have generated the interrupt.
If an interrupt is generated with a Mask 0000 0001 and if
you use the OR-PRIORITY logic, this variable gives the
input number, which have generated the interrupt.
