How to Use This Manual
Readers This manual is intended for users who wish to understand the functions of the
V850ES/JG3 and design application systems using the V850ES/JG3.
Purpose This manual is intended to give users an understanding of the hardware functions of the
V850ES/JG3 shown in the Organization below.
Organization This manual is divided into two parts: Hardware (this manual) and Architecture (V850ES
Architecture User’s Manual).
Hardware Architecture
• Pin functions • Data types
• CPU function • Register set
• On-chip peripheral functions • Instruction format and instruction set
• Flash memory programming • Interrupts and exceptions
• Electrical specifications • Pipeline operation
How to Read This Manual It is assumed that the readers of this manual have general knowledge in the fields of
electrical engineering, logic circuits, and microcontrollers.
To understand the overall functions of the V850ES/JG3
→ Read this manual according to the CONTENTS.
To find the details of a register where the name is known
→ Use APPENDIX C REGISTER INDEX.
Register format
→ The name of the bit whose number is in angle brackets (<>) in the figure of the register
format of each register is defined as a reserved word in the device file.
To understand the details of an instruction function
→ Refer to the V850ES Architecture User’s Manual available separately.
To know the electrical specifications of the V850ES/JG3
→ See CHAPTER 29 ELECTRICAL SPECIFICATIONS
The “yyy bit of the xxx register” is described as the “xxx.yyy bit” in this manual. Note with
caution that if “xxx.yyy” is described as is in a program, however, the compiler/assembler
cannot recognize it correctly.
