DESCRIPTION
The ST20 ANSI C Toolset provides a complete high
quality software development environment for the ST20
microcontroller and microprocessor. The compiler
supports the full ANSI C language definition and
includes both local and global optimizing features.
Embedded application support is provided by both
configuration and symbol map utilities.
An interactive windowing debugger provides single
stepping, breakpoints, watchpoints and many other
features for debugging sequential and multi-tasking
programs. Execution profilers give various post-mortem
statistical analyses of the execution of a program.
