interrupt
Description:
Controls the compilation of object code for interrupt routines.
Compatibility:
This pragma is compatible with the following platform targets:
Prototype:
#pragma interrupt on|off|reset
For Embedded PowerPC:
#pragma interrupt [SRR DAR DSISR enable] on | off | reset
Remarks:
When this option is on, the compiler generates a special prologue and epilogue for functions so that they may be used to handle interrupts.
For convenience, the compiler will also mark any interrupt function so that the linker does not dead-strip it. See "force_active" for related information.
Embedded 68K
When this option is on, the compiler generates a special prologue and epilogue for the functions encapsulated by this pragma. All modified registers (both nonvolatile and scratch registers) are saved or restored, and functions return via RETI instead of JMP [LP].
You can also use __declspec(interrupt) to mark functions as interrupt routines. For example:
__declspec(interrupt) void foo()
{
//enter code here
}
