Arguments

addr

Lowest CPU memory address to encode the data value.

...

MEM_VAL_COPY_SET_xxx() macros (see section 4-2-7) are more efficient than MEM_VAL_SET_xxx() macros and are also fully independent of CPU data-word-alignment and should be used whenever possible.

MEM_VAL_SET_xxx() macros are not atomic operations and must not be used on any non-static (i.e., volatile) variables, registers, hardware, etc.; without the caller of the macros providing some form of additional protection (e.g. mutual exclusion).
