+    *** 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")))".
