 * Internally its encoded as below with bit-fields representing error type, module and error code:\n\n
 * mbed_error_status_t Status Encoding:\n
 *
 \verbatim
 | 31 Always Negative | 30-29(2 bits)  | 28-24              | 23-16(8 bits) | 15-0(16 bits) |
 | -1                 | TYPE           | (unused/reserved)  | MODULE TYPE    | ERROR CODE    |
 \endverbatim
 *
 * The error status value range for each error type is as follows:\n
 *   Posix Error Status-es  - 0xFFFFFFFF to 0xFFFFFF01(-1 -255) - This corresponds to Posix error codes represented as negative.\n
 *   System Error Status-es - 0x80XX0100 to 0x80XX0FFF - This corresponds to System error codes range(all values are negative). Bits 23-16 will be module type(marked with XX)\n
 *   Custom Error Status-es - 0xA0XX1000 to 0xA0XXFFFF - This corresponds to Custom error codes range(all values are negative). Bits 23-16 will be module type(marked with XX)\n\n
 *
 * The ERROR CODE(values encoded into ERROR CODE bit-field in mbed_error_status_t) value range for each error type is also separated as below:\n
 *   Posix Error Codes  - 1 to 255.\n
 *   System Error Codes - 256 to 4095.\n
 *   Custom Error Codes - 4096 to 65535.\n
 *
 * @note Posix error codes are always encoded as negative of their actual value. For example, EPERM is encoded as -EPERM.
 *       And, the MODULE TYPE for Posix error codes are always encoded as MBED_MODULE_UNKNOWN.\n
 *       This is to enable easy injection of Posix error codes into MbedOS error handling system without altering the actual Posix error values.\n
 *       Accordingly, Posix error codes are represented as -1 to -255 under MbedOS error status representation.

 *  @note
 *  Custom Error codes can be defined using the macro DEFINE_CUSTOM_ERROR\n
 *  This is mainly meant to capture non-generic error codes specific to a device.
 *  For example DEFINE_CUSTOM_ERROR( MY_CUSTOM_ERROR ,1 ) macro defines the following values:\n
 *      ERROR_CODE_MY_CUSTOM_ERROR = MBED_CUSTOM_ERROR_BASE+1\n
 *      ERROR_MY_CUSTOM_ERROR = MAKE_MBED_ERROR(ERROR_TYPE_CUSTOM, MBED_MODULE_UNKNOWN, ERROR_CODE_MY_CUSTOM_ERROR)\n
 *  Its effectively equivalent to:\n
 *      ERROR_CODE_MY_CUSTOM_ERROR = 4097\n
 *      ERROR_MY_CUSTOM_ERROR = 0xA0FF1001\n (Note that MODULE field is set to MBED_MODULE_UNKNOWN) \n\n
 *
 *  @note
 *  **Using error codes:** \n
 *  Posix error codes may be used in modules/functions currently using Posix error codes and switching them to Mbed-OS error codes
 *  may cause interoperability issues. For example, some of the filesystem, network stack implementations may need to use
 *  Posix error codes in order to keep them compatible with other modules interfacing with them, and may continue to use Posix error codes.
 *
 *  In all other cases, like for any native development of Mbed-OS modules Mbed-OS error codes should be used.
 *  This makes it easy to use Mbed-OS error reporting/logging infrastructure and makes debugging error scenarios
 *  much more efficient.
 *
 *  @note
 *  **Searching for error codes in mbed-os source tree:** \n
 *  If you get an error report as below which you want to search for in mbed-os source tree, first take note of "Error Code" number. \n
 *  For example, the below error report has an error code of \b 259. Find the error name associated with the error code and in this case its \b INVALID_FORMAT. \n
 *  Use that error name(\b INVALID_FORMAT) to search the source tree for code locations setting that specific error code. \n
 *  If the Error module reported is not 255(which indicates unknown module), you can also use that to narrow down to the specific component reporting the error.
 *  See mbed_module_type_t enum above for module mapping. \n

 *
 * @code
 * #error "That shouldn't have happened!"
 * @endcode
 *
 * If the compiler evaluates this line, it will report the error and stop the compile.
 *
 * For example, you could use this to check some user-defined compile-time variables:
 *
 * @code
 * #define NUM_PORTS 7
 * #if (NUM_PORTS > 4)
 *     #error "NUM_PORTS must be less than 4"
 * #endif
 * @endcode
 *
 * Reporting Run-Time Errors:
 * To generate a fatal run-time error, you can use the mbed error() function.
 *
 * @code
 * error("That shouldn't have happened!");
 * @endcode
 *
 * If the mbed running the program executes this function, it will print the
 * message via the USB serial port, and then die with the blue lights of death!
 *
 * The message can use printf-style formatting, so you can report variables in the
 * message too. For example, you could use this to check a run-time condition:
 *
 * @code
 * if(x >= 5) {
 *     error("expected x to be less than 5, but got %d", x);
