Hi,

Is it possible to add a syscall/instruction/pseudo-instruction to the simulator? I have to set a bit in the simulator from the program using this instruction. If yes, could you please shed some light on how to do this?

Thanks for your time and any comments are welcome. Regards, Saideepak.

Can I write a ptlcall for this purpose?
