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 “<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 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.
 When you know a register name and want to confirm its details:
 Refer to APPENDIX B REGISTER INDEX.
 To know details of the 78K0 microcontroller instructions:
 Refer to the separate document 78K/0 Series Instructions User’s Manual
(U12326E).
