COMPATIBILITY
<From another C compiler to this C compiler>
• Modification is not needed if the compiler does not use the functions for data insertion.
• To change to functions for data insertion, modify according to USAGE above.
<From this C compiler to another C compiler>
• Function names for data insertion can be used as function names by deleting the #pragma opc statement or
delimiting it with #ifdef.
• To use as a function for data insertion, modify the program according to the specifications of each C compiler
(#asm, #endasm or asm() ; , etc.).
