How to Use This Manual
www.DataSheet4U.com
It is assumed that the readers of this manual have general knowledge of electrical
engineering, logic circuits, and microcontrollers.
◊ To understand the overall functions of 78K0S/KY1+
→ Read this manual in the order of the CONTENTS. The mark <R> shows major
revised points. The revised points can be easily searched by copying an “<R>”
in the PDF file and specifying it in the “Find what:” field.
◊ How to read register formats
→ For a bit number enclosed in angle brackets (<>), the bit name is defined as a
reserved word in the RA78K0S, and is defined as an sfr variable using the
#pragma sfr directive in the CC78K0S.
◊ To learn the detailed functions of a register whose register name is known
→ See APPENDIX B REGISTER INDEX.
◊ To learn the details of the instruction functions of the 78K/0S Series
→ Refer to 78K/0S Series Instructions User’s Manual (U11047E) separately
available.
◊ To learn the electrical specifications of the 78K0S/KY1+
→ See CHAPTER 19 and CHAPTER 20 ELECTRICAL SPECIFICATIONS.
