INTRODUCTION
Readers This manual has been prepared for user engineers who understand the functions
of the
µ
PD78078 and 78078Y Subseries and design and develop its application
systems and programs.
The
µ
PD78078 and 78078Y Subseries consist of the following members.
•
µ
PD78078 Subseries:
µ
PD78076, 78078, 78P078
•
µ
PD78078Y Subseries:
µ
PD78076Y, 78078Y, 78P078Y
Caution Of the above members, the following devices with the suffix
KL-T should be used only for experiment or function evaluation,
because they are not intended for use in equipment that will be
mass-produced and do not have enough reliability.

How to Read This Manual Before reading this manual, you should have general knowledge of electric and
logic circuits and microcontroller.
When you want to understand the functions in general:
→ Read this manual in the order of the contents.
How to interpret the register format:
→
For the circled bit number, the bit name is defined as a reserved word in RA78K/
0, and in CC78K/0, already defined in the header file named sfrbit.h.
When you know a register name and want to confirm its details:
→ Read “APPENDIX D REGISTER INDEX”
To know the differences between the
µ
PD78054 and 78054Y Subseries:
→ See sections 1.10 and 2.10, titled “Differences with
µ
PD78054 Subseries”
and “Differences with
µ
PD78054Y Subseries”, respectively.
To know the
µ
PD78078 and 78078Y Subseries instruction function in detail:
→ Refer to “78K/0 Series User’s Manual—Instructions (U12326E)”
To know the application example of each function of the
µ
PD78078 and 78078Y
Subseries:
→ Refer to separately available Application Note.
