Hi !

We are writing a program based on 89C51, this is a telecom project.

Presently We are using Atmel 89C52, and external ep rom 27C010 and "C" with useing C51 compiler.

our Code size is presently around 63K mean almost full.

We compile full code and program 8 k in microcontroller and rest in ep rom.

Now we wanted to break the code in 2 parts, 1st for micro controller, that is fixed and 2nd for ep-rom that is changable, when we found any bug, we wanted to change the code and micro controller is fixed.

when ever we found the bug, we have to send the microcontroller as well as ep-rom.

Now our team leader told: that is not possible due to we are using C51 and in this we don't have any command where to store the data or memory location. If we write a program in assembly, than it is possible.

please suggest, can we do this with using C51 complier.

thanks for your support.
