COMPATIBILITY
<From another C compiler to this C compiler>
• The C source program need not be modified if interrupt functions are not used at all.
• To change an ordinary function to an interrupt function, modify the program according to the procedure
described in USAGE above.
<From this C compiler to another C compiler>
• DI and EI can be used as ordinary function names (example: #ifdef_ _K0S_ _ ... #endif) by deleting the
#pragma DI and #pragma EI directives or delimiting them with #ifdef.
• To use an ordinary function as an interrupt function, modify the program according to the specifications of
each compiler.
