|

20 | Functions that are be executed in RAM should reside in a separate
|

21 | source module. Using the 'Options for File' dialog you can simply change
|
---|
22 | the 'Code / Const' area of a module to a memory space in physical RAM.
|

23 | Available memory areas are declared in the 'Target' tab of the
|

24 | Options for Target' dialog.
