     RAM functions are defined using the toolchain options. 
     Functions that are executed in RAM should reside in a separate source module.
     Using the 'Options for File' dialog you can simply change the 'Code / Const' 
     area of a module to a memory space in physical RAM.
     Available memory areas are declared in the 'Target' tab of the 'Options for Target'
     dialog.
