USING THE FULL 256K MEMORY SPACE

Applies to: C251 C Compiler

Answer

QUESTION

I have v1.13 of the C251 compiler. I want to use the full 256K of memory space. How can I do that?

ANSWER

The linker in the Version 1 tools does not directly support more than 128K of memory. 64K is for code, and 64K is data space. If you need more memory space with the Version 1 tools, you must use a bank-switching scheme. See the file in the 251 directory called v1.1 enhancements for details on how to do bank linking.

Updates for C251 Version 2 are available on the web site at the following URL:

This version supports more than 128K.
