Explanation of each instruction
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 assembler, and is defined as an sfr variable using the #pragma sfr directive in the
compiler.
●
To know details of the RL78/G15 Microcontroller instructions:
→ Refer to the separate document RL78 Family User’s Manual: Software (R01US0015E).
