+ * @verbatim
+
+ *** ARM Compiler ***
+ --------------------
+ [..] RAM functions are defined using the toolchain options.
+ Functions that are be 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.
+
+ *** ICCARM Compiler ***
+ -----------------------
+ [..] RAM functions are defined using a specific toolchain keyword "__ramfunc".
+
+ *** GNU Compiler ***
+ --------------------
+ [..] RAM functions are defined using a specific toolchain attribute
+ "__attribute__((section(".RamFunc")))".
