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.
