* @brief Error checking module.
* @details
* By default, EMLIB library assert usage is not included in order to reduce
* footprint and processing overhead. Further, EMLIB assert usage is decoupled
* from ISO C assert handling (NDEBUG usage), to allow a user to use ISO C
* assert without including EMLIB assert statements.
*
* Below are available defines for controlling EMLIB assert inclusion. The defines
* are typically defined for a project to be used by the preprocessor.
*
* @li If @ref DEBUG_EFM is defined, the internal EMLIB library assert handling will
* be used. This is implemented as a simple while(true) loop. @ref DEBUG_EFM is not
* defined by default.
*
* @li If DEBUG_EFM_USER is defined instead, the user must provide their own
* implementation of the assertEFM() function.
*
* @li If both @ref DEBUG_EFM and DEBUG_EFM_USER are undefined then all EFM_ASSERT()
* statements are no operation.
*
* @note
* The internal EMLIB assert is documented here because @ref DEBUG_EFM is defined in
* the doxygen configuration.
