BEFORE USING THIS USER’S MANUAL
This user’s manual consists of the following three chapters. Refer to the chapter appropriate to your conditions, such
as hardware design or software development. Chapter 3 also includes necessary information for systems development.
Be sure to refer to this chapter.
1. Organization
G
CHAPTER 1 HARDWARE
This chapter describes features of the microcomputer and operation of each peripheral function.
G
CHAPTER 2 APPLICATION
This chapter describes usage and application examples of peripheral functions, based mainly on setting examples
of related registers.
G
CHAPTER 3 APPENDIX
This chapter includes necessary information for systems development using the microcomputer, electric
characteristics, a list of registers, the masking confirmation (mask ROM version), and mark specifications which
are to be submitted when ordering.
2. Structure of register
The figure of each register structure describes its functions, contents at reset, and attributes as follows :
Note 2. Bit attributesThe attributes of control register bits are classified into 3 bytes : read-only, write-only
and read and write. In the figure, these attributes are represented as follows :
: Bit in which nothing is arranged
