When defining an integral constants as a macro, please tell me how to prevent the final operation result from becoming a negative number.
- By adding a suffix to the number to indicate that it is an unsigned integer, it is possible to prevent the operation result from becoming a negative number.
  #define MACRO_DATA1 (63UL)
  Here, the number is defined as an unsigned long type by adding a suffix (UL: unsigned long) to the number.
  For the suffix, see "2.2.4.1 Integral Constants" in the CCU8 Language Reference Manual.
