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