i m working on a project based on 8051 family micontrollers AT89c51RC
My problem in this project is the software gets restart from the beginning of main function when it is executing somewhere between the program.
this problem occurs randomly not alwayz.
This occurs when controller gets an External interrupt from other controller .
PLz reply as soon as possible

As told by u tht there can be a stack problem but plz tell me in detail how to check the stack status . i m doing coding in Micro C.
I m using AT89C51RC controller in which there r 512bytes of RAM as well as other controller Philips made P89C51RD2 which has 1 KB RAM .
but in both controllers the same problem is present.
Plz tell the method to use Expanded On chip RAM of both this controllers using Micro C.
I m working on a micro c compiler of Dunfield company in which there r five memory models and i m using the tiny memory model in which they have a feature of only 128/256 bytes RAM .

PLz reply as soon as possible.

Also i cant post my code as i m working in a company where i m not allowed to do that.
