Arguments

addr

Lowest CPU memory address to encode the data value.

...

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).

Example Usage

          CPU_INT08U  *pval;
          CPU_INT16U   val;


          pval = &SomeAddr;              /* Any CPU address */
          val =  0xABCDu;
          MEM_VAL_SET_INT16U(pval, val);
