How to Read This Manual Before reading this manual, you should have general knowledge of electric and logic
circuits and microcontrollers.
For users who use this document as the manual for the
µ
PD78052(A), 78053(A),
and 78054(A):
→The only differences between the
µ
PD78052, 78053, and 78054 and the
µ
PD78052(A), 78053(A), 78054(A) are the quality grades and packages. (refer
to 1.9 Differences between Standard Quality Grade Products and (A) Products).
For the (A) products, read the part numbers in the following manner.
µ
PD78052 →
µ
PD78052(A)
µ
PD78053 →
µ
PD78053(A)
µ
PD78054 →
µ
PD78054(A)
When you want to understand the functions in general:
→Read this manual in the order of the contents.
To know the
µ
PD78054 and 78054Y Subseries instruction function in detail:
→ Refer to the 78K/0 Series User's Manual: Instructions (U12326E)
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.
To learn the function of a register whose register name is known:
→ Refer to Appendix D Register Index.
To know the electrical specifications of the
µ
PD78054 and 78054Y Subseries:
→ Refer to separately available Data Sheet.
To know application examples of the functions provided in the
µ
PD78054 and
78054Y Subseries:
→ Refer to Application Note separately provided.
Caution The application examples in this manual are created for “Standard” quality
grade products for general electric equipment. When using the application
examples in this manual for purposes which require “Special” quality grades,
thoroughly examine the quality grade of each part and circuit actually used.
