Code Placement#

Code Placement API.

Provides support for executing code from RAM rather than flash memory. Note

• Inlined functions are placed wherever the calling function resides.

Use Cases#

Consider placing code in RAM when:

• The function is performance-critical and called frequently

• The function must execute with minimal latency

• The function is called during flash operations (erase/write)

• Deterministic timing is required (eliminates flash wait states)

Linker Requirements#

The linker script must define the appropriate RAM section "text_application_ram" for code placement.

The "text_application_ram" section is pre-configured in Silicon Labs linker scripts, but custom linker scripts must include the "text_application_ram" section.

Usage#

In your .h file:

#include "sl_code_classification.h"

SL_CODE_RAM
void MyPrint(const char* string);
