STUB Function

This section describes the STUB function which executes commands automatically
when the breakpoint hit occurs.

■ Outline of 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.

■ How to set

The STUB function can be set by the following commands.
