CHAPTER 8DEBUGGER
This chapter describes how to use the Debugger db63.
8.1 Features
The Debugger db63 is used to debug a program after reading an object file in the IEEE-695 format that is
generated by the linker.
It has the following features and functions:
•Various data can be referenced at the same time using multiple windows.
•Frequently used commands can be executed from tool bars and menus using a mouse.
• Also available are source display and symbolic debug functions which correspond to assembly source
codes.
• Consecutive program execution and two types of single-stepping are possible.
• Five break functions are supported.
•A real-time display function shows register and memory contents on-the-fly.
•A time display function showing execution time by both duration and steps.
• An advanced trace function.
•An automatic command execution function using a command file.

8.2.1 Input Files
Parameter file
File format: Binary file
File name: <file name>.par
Description: This file contains memory information on each microcomputer model and is indispensable
for starting the debugger. This file is provided for each microcomputer model.
The following files are read by the debugger according to command specification.
Object file
File format: Binary file in the IEEE-695 format
File name: <file name>.abs (An extension other than ".abs" can also be used.)
Description: This is an object file generated by the linker. This file is read into the debugger by the lf
command. By reading a file in the IEEE-695 format that contains debug information, source
display and symbolic debugging can be performed.
