I am using MC9S12eq512 with code warrior in my project. this controller contain 32k but default we can access only 8k RAM area. I want to increase my RAM area . please helpme how will configure the PRAM area in my project.
Probably you meant MC9S12XEQ512?
It depends on what are you going to do with this RAM. In case all your data arrays are <=4kB (which is size of RAM R-page window), just surrend your banked RAM variable declarations and definitions with two pragmas.
#pragma DATA_SEG __RPAGE_SEG PAGED_RAM
//add your data here
#pragma DATA_SEG DEFAULT
Depending on your code you may need to change setting of Compiler for HC12 -> Code Generation -> Assume objects are in same page for = never for different objects.
