COMPATIBILITY
<From another C compiler to this C compiler>
• The C source program need not be modified if the CPU control instructions are not used.
• Modify the program according to the procedure described in USAGE above when the CPU control instructions
are used.
<From this C compiler to another C compiler>
• HALT, STOP, and NOP can be used as function names by deleting the “#pragma HALT”, “#pragma STOP”,
and “#pragma NOP” statements or delimiting them with #ifdef.
• To use these instructions as the CPU control instructions, modify the program according to the specifications
of each compiler (such as #asm, #endasm, and asm();).
