indirect call

[Eric_t]

Hi, everybody

I have to make an indirect call or jump but i do not know how to do it.

For example i have to make the following jump or call: 

                               Address FE00: CA 00 54 78 53 FA ....

                              I have to make a jump or call at the address which

                              contained in address FE00 (jump to CA00 address). 

Can anyone tell me how can i do it in assemby or C?

I am using the mc9s12dg256 controller and codewarrior v3.1. 

Thanks

Nikos

asm:

asm{

   LDX   0xFE00

   JMP   0,X

}

C:

typedef void (** near pfptr)(void);

{

   (*((pfptr)(void*)0xFE00))(); // jump to subroutine, whose 16bit address is stored at 0xFE00

}
