3.1
The interactive debugger consists of a host-based symbolic debugger and a target-resident debug-
ging kernel that is configured into the application program on an ST20 processor.
The interactive debugger provides the following features:–
ST20–SWC

Interactive debugging
A break point facility that can be used on particular threads of execution.
A single stepping facility that allows a thread of execution to be single stepped at the source
level or at the assembly code level.
A watch point facility that enables the program to be stopped when variables are to be written
to or read from.
A facility to find the threads of execution of a program and set break points on them.
A stack trace facility.
A facility to monitor the creation of threads of execution.
Commands to print the values of variables and display memory.
Commands to modify variables and memory at run time.
A simple interpreter to enable C aggregate types (i.e. structures and arrays) to be displayed.
A programmable command language that allows complex break points and watch points to
be set and enables debugging scripts to be generated.
A source and object browser to select a process, a thread and source code.
An interface to the real-time operating system for dynamic code loading and thread creation.
