The 78K0/LC3 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/LC3 and design and develop application systems and programs for these devices.
The target products are as follows.
78K0/LC3: μPD78F0400, 78F0401, 78F0402, 78F0403
μPD78F0410, 78F0411, 78F0412, 78F0413
This manual is intended to give users an understanding of the functions described in the
Organization below.
The 78K0/LC3 manual is separated into two parts: this manual and the instructions
edition (common to the 78K0 microcontrollers).

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.
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 know details of the 78K0 microcontroller instructions:
Refer to the separate document 78K/0 Series Instructions User’s Manual
(U12326E).
Conventions
Data significance:
Higher digits on the left and lower digits on the right
Active low representations: ××× (overscore over pin and signal name)
Note:
Footnote for item marked with Note in the text
Caution:
Information requiring particular attention
Remark:
Supplementary information
Numerical representations: Binary
