segment CODE = IRAM

Available settings for I_RAM:

- ON

- OFF

Example:

The code in the segment IRAM should be copied to the instruction RAM during startup.

#set

I_RAM

;

2.5 Low-Level Library Interface (CLIBINIT)

The setting CLIBINI specifies whether the startup code has to call the stream initialization

function of the C-library.

The stream initialization is necessary only, if streamed IO-functions are used. These

functions (e.g. printf()) also require the definition of application specific low-level functions.

For more information refer to the compiler help.

Available settings for CLIBINIT:

- ON

- OFF

Example:

The stream initialization should not be done.

#set

CLIBINIT

2.6 C++ startup (CPLUSPLUS)

In the C++ specifications, when external or static objects are used, a constructor must be

called followed by the main function. Because four-byte pointers to the main function are

stored in the EXT_CTOR_DTOR section, call a constructor sequentially from the lower

address of the four addresses in that section. If using C++ sources, activate this function to

create the section EXT_CTOR_DTOR.

Available settings for CPLUSPLUS:

- ON

- OFF

Example:

C++ is not used.

#set

CPLUSPLUS
