User’s Manual U15556EJ1V0UM

[Target Devices]

Software for the 78K/IV Series microcontrollers can be developed with this C compiler.

Note that the device file (sold separately) corresponding to the target device is necessary.

[Target Readers]

Although this manual is intended for those who have read the user's manual of the microcontroller subject to software

development and have experience in software programming, the reader need not necessarily have knowledge of C

compilers or C language. Discussions in this manual assume that readers are familiar with software terminology.

[Organization]

This manual consists of the following 13 chapters and appendixes.

CHAPTER 1 GENERAL

Outlines the general functions of C compilers and the performance characteristics and features of this

C compiler.

CHAPTER 2 CONSTRUCTS OF C LANGUAGE

Explains the constituent elements of a C source module file.

CHAPTER 3 DECLARATION OF TYPES AND STORAGE CLASSES

Explains the data types and storage classes used in C and how to declare the type and storage class

of a data object or function.

CHAPTER 4 TYPE CONVERSIONS

Explains the conversions of data types to be automatically carried out by this C compiler.

CHAPTER 5 OPERATORS AND EXPRESSIONS

Describes the operators and expressions that can be used in C and the priority of operators.

CHAPTER 6 CONTROL STRUCTURES OF C LANGUAGE

Explains the program control structures of C and the statements to be executed in C.

CHAPTER 7 STRUCTURES AND UNIONS

Explains the concept of structures and unions and how to refer to structure and union members.

CHAPTER 8 EXTERNAL DEFINITIONS

Describes the types of external definitions and how to use external declarations.

CHAPTER 9 PREPROCESSING DIRECTIVES

Details the types of preprocessing directives and how to use each preprocessing directive.

CHAPTER 10 LIBRARY FUNCTIONS

Details the types of C library functions and how to use each library function.

CHAPTER 11 EXTENDED FUNCTIONS

Explains the extended functions of this C compiler provided to make the most of the target device.

CHAPTER 12 REFERENCING BETWEEN C AND ASSEMBLER

Describes the method of linking a C source program with a program written in assembly language.

CHAPTER 13 EFFECTIVE UTILIZATION

Outlines how to effectively use this C compiler.

APPENDIXES A through E

Contain a list of labels for saddr area, a list of segment names, a list of runtime libraries, a list of library

stack consumption, and an index for quick reference.
