/**
 * @file cm_debug.c
 * @brief A common way of error reporting and debugging messages
 * @detail This section handles all the error reporting
 *		   features in all sections. Using this section
 *		   the programmer can debug the code (finding the
 *		   line number, section, function name). To enable
 *		   this feature programmer need to enable 'CM_DEBUG_'
 *		   at compile time.
