How to Read This Manual It is assumed that the readers of this manual have general knowledge of electrical
engineering, logic circuits, and microcontrollers.
•
When using this manual as the manual for (A) products and (A1) products:
→ Only the quality grade differs between standard products and (A) and (A1)
products. Read the part number as follows.
• µPD780143 → µPD780143(A), 780143(A1)
• µPD780144 → µPD780144(A), 780144(A1)
• µPD780146 → µPD780146(A), 780146(A1)
• µPD780148 → µPD780148(A), 780148(A1)
• µPD78F0148 → µPD78F0148(A)
•
•
To gain a general understanding of functions:
→ Read this manual in the order of the CONTENTS.
How to interpret the register format:
→ For a bit number enclosed in square, the bit name is defined as a reserved word
in the assembler, and is already defined in the header file named sfrbit.h in the C
compiler.
•
To check the details of a register when you know the register name.
→ Refer to APPENDIX C REGISTER INDEX.
