4.3.4 Additional Preprocessor Functions
The Preprocessor pp33 offers additional functions for the creation of assembly source files. This section will deal
only with the notations for these functions. For details on each one of the functions, refer to Chapter 9,
"Preprocessor". The preprocessor processes the notations of the said functions into mnemonic statements that can
be assembled, thereby delivering assembly source files.
Note: The statements dealt with in this section need to be processed by the preprocessor, and cannot

Operators
S5U1C33000C MANUAL
(C COMPILER PACKAGE FOR S1C33 FAMILY) (Ver. 4)
The following five types of pseudo-instructions are provided for the Preprocessor pp33.
#include
#define
#macro–#endm
#ifdef(ifndef)–#else–#endif
All of these pseudo-instructions begin with a sharp (#).
Examples: #include
For details on the notation of each pseudo-instruction and function, refer to Section 9.5 "Preprocessor
Pseudo-Instructions".
To specify a value in the source, an expression using the following operators can be used:
In the numeric parts of an expression, you can use a symbol whose value is defined by the preprocessor
pseudo-instruction #define.
