The µPD78F0527D has an on-chip debug function.
Do not use this product for mass production because its reliability cannot be guaranteed after the on-chip debug function
has been used, due to issues with respect to the number of times the flash memory can be rewritten. NEC Electronics
does not accept complaints concerning this product.

INTRODUCTION
Readers
Purpose
Organization
This manual is intended for user engineers who wish to understand the functions of the
78K0/KD2 and design and develop application systems and programs for these devices.
The target products are as follows.
78K0/KD2: µPD78F0521, 78F0522, 78F0523, 78F0524, 78F0525, 78F0526, 78F0527,
78F0527D
This manual is intended to give users an understanding of the functions described in the
Organization below.
The 78K0/KD2 manual is separated into two parts: this manual and the instructions
edition (common to the 78K/0 Series).

Explanation of each instruction
How to Read This Manual It is assumed that the readers of this manual have general knowledge of electrical
engineering, logic circuits, and microcontrollers.
To gain a general understanding of functions:
Read this manual in the order of the CONTENTS. The mark shows major
revised points.
How to interpret the register format:
For a bit number enclosed in angle brackets, the bit name is defined as a
reserved word in the RA78K0, and is defined as an sfr variable using the
#pragma sfr directive in the CC78K0.
To check the details of a register when you know the register name:
See APPENDIX C REGISTER INDEX.
To know details of the 78K/0 Series instructions:
Refer to the separate document 78K/0 Series Instructions User’s Manual
(U12326E).
