bogdanm 0:9b334a45a8ff 20 [..] RAM functions are defined using the toolchain options.
bogdanm 0:9b334a45a8ff 21 Functions that are executed in RAM should reside in a separate
bogdanm 0:9b334a45a8ff 22 source module. Using the 'Options for File' dialog you can simply change
bogdanm 0:9b334a45a8ff 23 the 'Code / Const' area of a module to a memory space in physical RAM.
bogdanm 0:9b334a45a8ff 24 Available memory areas are declared in the 'Target' tab of the
