* @brief Used to specify the PrdfMemoryMru type.
*
* One requirement for all memory MRUs is that it must be able to be
* converted into a 32-bit representation of the object. This number is then
* passed around is different places, one in particular is word 9 of the
* SRC. Eventually, data will need to be retrieved from the number. Since
* the structure of each memory MRU may change, bits[0:2] of the 32-bit
* number is reserved for the version type of the memory MRU. Based on the
* version a new memory MRU can be constructed.
*
* NOTE: The reason MEMMRU_ECLIPZ starts with 3 is because in the original
* P6 memory MRU there was a 4-bit field for the version type in which
* the value was 6 (for P6). To save as much space as possible the
* version field was reduced to 3 bits and the P6 version as changed
* to 3. Thus, saving a bit of space without compromising the value of
* that field.
