CHAPTER 2 DEPENDENCE FUNCTIONS
2.1.8 STUB Function

This section describes the STUB function which executes commands automatically when

the breakpoint hit occurs.

■STUB Function

The STUB function is supported so that a series of commands in the command list can automatically be
executed when a specified breakpoint is hit. The use of this function enables spot processing, such as simple
I/O simulation, external interrupt generation, and memory reprogramming, without changing the main
program. This function is effective only when the simulator debugger is used.
■Setting Method
The STUB function can be set by the following commands.
• Dialog
1. Breakpoint Set Dialog - [Code] tab
2. Breakpoint Set Dialog - [Data] tab
• Command
