*
* Note(s) : (1) (a) Some variables & variable buffers to pass & receive data values MUST start on appropriate
*                   CPU word-aligned addresses.  This is required because most word-aligned processors are more
*                   efficient & may even REQUIRE that multi-octet words start on CPU word-aligned addresses.
*
*                   (1) For 16-bit word-aligned processors, this means that
*
*                           all 16- & 32-bit words MUST start on addresses that are multiples of 2 octets
*
*                   (2) For 32-bit word-aligned processors, this means that
*
*                           all 16-bit       words MUST start on addresses that are multiples of 2 octets
*                           all 32-bit       words MUST start on addresses that are multiples of 4 octets
*
*               (b) However, some data values macro's appropriately access data values from any CPU addresses,
*                   word-aligned or not.  Thus for processors that require data word alignment, data words can
*                   be accessed to/from any CPU address, word-aligned or not, without generating data-word-
*                   alignment exceptions/faults.

*                       MEM_VAL_GET_xxx()               Decode data values using CPU's native or configured

*
*                   See also 'cpu.h  CPU WORD CONFIGURATION  Note #2'.
*
*               (2) CPU memory addresses/pointers NOT checked for NULL.
*
*               (3) (a) MEM_VAL_GET_xxx() macro's decode data values without regard to CPU word-aligned addresses.
*                       Thus for processors that require data word alignment, data words can be decoded from any
*                       CPU address, word-aligned or not, without generating data-word-alignment exceptions/faults.
*
*                   (b) However, any variable to receive the returned data value MUST start on an appropriate CPU
*                       word-aligned address.
*
*                   See also 'MEMORY DATA VALUE MACRO'S  Note #1'.
*
*               (4) MEM_VAL_COPY_GET_xxx() macro's are more efficient than MEM_VAL_GET_xxx() macro's & are 
*                   also independent of CPU data-word-alignment & SHOULD be used whenever possible.
*
*                   See also 'MEM_VAL_COPY_GET_xxx()  Note #4'.
*
*               (5) The 'CPU_CFG_ENDIAN_TYPE' pre-processor 'else'-conditional code SHOULD never be compiled/
*                   linked since each 'cpu.h' SHOULD ensure that the CPU data-word-memory order configuration

*
* Description : Copy & decode data values from any CPU memory address to any CPU memory address.
*
* Argument(s) : addr_dest       Lowest CPU memory address to copy/decode source address's data value 
*                                   (see Notes #2 & #3).
*
*               addr_src        Lowest CPU memory address of data value to copy/decode 
*                                   (see Notes #2 & #3).
*
* Return(s)   : none.
*
* Caller(s)   : various.
*
* Note(s)     : (1) Copy/decode data values based on the values' data-word order :
*
*                       MEM_VAL_COPY_GET_xxx_BIG()      Decode big-   endian data values -- data words' most
*                                                           significant octet @ lowest memory address
*                       MEM_VAL_COPY_GET_xxx_LITTLE()   Decode little-endian data values -- data words' least
*                                                           significant octet @ lowest memory address
*                       MEM_VAL_COPY_GET_xxx()          Decode data values using CPU's native or configured 
*                                                           data-word order
*
*                   See also 'cpu.h  CPU WORD CONFIGURATION  Note #2'.
*
*               (2) CPU memory addresses/pointers NOT checked for NULL.
*
*               (3) MEM_VAL_COPY_GET_xxx() macro's copy/decode data values without regard to CPU word-aligned 
*                   addresses.  Thus for processors that require data word alignment, data words can be copied/
*                   decoded to/from any CPU address, word-aligned or not, without generating data-word-alignment 
*                   exceptions/faults.
*
*               (4) MEM_VAL_COPY_GET_xxx() macro's are more efficient than MEM_VAL_GET_xxx() macro's & are 
*                   also independent of CPU data-word-alignment & SHOULD be used whenever possible.
*
*                   See also 'MEM_VAL_GET_xxx()  Note #4'.
*
*               (5) Since octet-order copy/conversion are inverse operations, memory data value gets/sets are
*                   inverse operations.
*
*                   See also 'MEM_VAL_COPY_SET_xxx()  Note #5'.
*
*               (6) The 'CPU_CFG_ENDIAN_TYPE' pre-processor 'else'-conditional code SHOULD never be compiled/
*                   linked since each 'cpu.h' SHOULD ensure that the CPU data-word-memory order configuration
*                   constant (CPU_CFG_ENDIAN_TYPE) is configured with an appropriate data-word-memory order 
*                   value (see 'cpu.h  CPU WORD CONFIGURATION  Note #2').  The 'else'-conditional code is 
*                   included as an extra precaution in case 'cpu.h' is incorrectly configured.
