how to get stack pointer (SP)

mikoran — Mon, 28 Jul 2008 09:33:29 GMT

can you help me get the value of the stack pointer?

i am working on a module where I would monitor the value of the stack pointer and the program counter upon access violation.

I have this code in my interrupt handler:

    ISR void CPU12MPU_ISR(void) {
        __asm sts u16sp
        __asm movw 8,SP,u16pc

        S12XAccessViolation_ISR();
    }

The problem with this code was it will have an endless loop executing __asm sts u16sp.

Is there any way I could get the value of SP?

Thanks
