ASSERT - Assert
Assert/error checking module.
This module contains functions to control the ASSERT peripheral of Silicon Labs 32-bit MCUs and SoCs.
By default, EMLIB library assert usage is not included to reduce footprint and processing overhead. Further, EMLIB assert usage is decoupled from ISO C assert handling (NDEBUG usage) to allow using ISO C assert without including EMLIB assert statements.
Below are available defines for controlling EMLIB assert inclusion. The defines are typically for a project to be used by the preprocessor.
- If DEBUG_EFM is defined, the internal EMLIB library assert handling will be used. This is implemented as a simple while(true) loop. DEBUG_EFM is not defined by default.
- If DEBUG_EFM_USER is defined, the user must provide custom implementation of the assertEFM() function.
- If both DEBUG_EFM and DEBUG_EFM_USER are undefined, all EFM_ASSERT() statements are not operational.
- The internal EMLIB assert is documented because DEBUG_EFM is defined in the doxygen configuration.

|void assertEFM||(||const char *||
EFM internal assert handling.
This function is invoked through EFM_ASSERT() macro usage only and should not be used explicitly.
This implementation enters an indefinite loop, allowing the use of a debugger to determine a cause of failure. By defining DEBUG_EFM_USER to the preprocessor for all files, a user-defined version of this function must be defined and will be invoked instead, possibly providing output of assertion location.
- This function is not used unless DEBUG_EFM is defined during preprocessing of EFM_ASSERT() usage.
Name of the source file where assertion failed. [in]
