How to allocate group of variables to the same address?

Latest Updated:05/18/2015


I am using the CC-RL compiler for RL78 devices. Since I am using specified ranges of RAM for different purposes depending on the program, I want to allocate groups of variables for given purposes to the same addresses. How do I do this?


Divide the groups of variables into individual sections, and allocate them to the same addresses by using the colon (:) with the linker’s –start option.


Allocating sections .C, .D, and .F to the address 0xffe20.
