Aim MIL-STD-1553 - Apiinstinthandler

36 MIL-STD-1553 Reference Manual
Chapter 2 - Library Administration and Initialization Functions
2.1.16 ApiInstIntHandler
Prototype:
AiInt16 ApiInstIntHandler ( AiUInt32 ul_ModuleHandle, AiUInt8 biu, AiUInt8 uc_Type,
TY_INT_FUNC_PTR pf_IntFunc );
Driver Command:
none
Purpose:
This function is used to install a user-defined interrupt handler function. It is possible
to define interrupt handler functions for BC, RT, BM, Replay and BC-Branch related
interrupts. If there is the need for an interrupt handler function that handles several
interrupt types (BC, RT, BM, Replay, BC-Branch), it is necessary to call this function
for all different interrupt types (BC, RT, BM, Replay or BC-Branch), each with the same
given interrupt handler function "pf_IntFunc".
Note: To install a HS-Interrupt-Handler when working with a 3910-Board, the “biu”
parameter shall be set to “API_BIU_2” !!!
