00038  * @{
00039  * @details Error codes are 32-bit unsigned integers with the most significant 16-bit reserved for
00040  *          identifying the module where the error occurred while the least least significant LSB
00041  *          are used to provide the cause or nature of error. Each module is assigned a 16-bit
00042  *          unsigned integer. Which it will use to identify all errors that occurred in it. 16-bit
00043  *          LSB range is with module id as the MSB in the 32-bit error code is reserved for the
00044  *          module. As an example, if 0x8800 identifies a certain SDK module, all values from 
00045  *          0x88000000 - 0x8800FFFF are reserved for this module.
00046  *          It should be noted that common error reasons have been assigned values to make it 
00047  *          possible to decode error reason easily. As an example, lets module uninitialized has
00048  *          been assigned an error code 0x000A0. Then, if application encounters an error code
00049  *          0xZZZZ00A0, it knows that it accessing a certain module without initializing it.
00050  *          Apart from this, each module is allowed to define error codes that are not covered by
00051  *          the common ones, however, these values are defined in a range that does not conflict
00052  *          with common error values. For module, specific error however, it is possible that the
00053  *          same error value is used by two different modules to indicated errors of very different
00054  *          nature. If error is already defined by the NRF common error codes, these are reused.
00055  *          A range is reserved for application as well, it can use this range for defining
00056  *          application specific errors.
00057  *
00058  * @note Success code, NRF_SUCCESS, does not include any module identifier.
