S8051.DLL or TP51.DLL Arguments

Does anyone know what are the arguments for this DLLs? I am using an older Keil system uvision2 (I can't afford the new one).

I am trying to debug a CY7C68013A Cypress 8051 controller. I can't seem to be able to debug my program without Keil complaining it lost sync with the target. I have replaced the DLL Monitor provided by Cypress, however I don't know what arguments to pass to it.

when it comes up by default it comes with -pFX2, other examples provided by cypress start with -p52. I don't know what to put there to stop it from crashing.

Any help will be appreciated.
