The ICG has several features which can provide protection to the
microcontroller if properly used. Other features can greatly simplify
usage of the ICG if certain techniques are employed. This section
describes several possible ways to use the ICG and its features. These
techniques are not the only ways to use the ICG and may not be
optimum for all environments. In any case, these techniques should be
used only as a template, and the user should modify them according to
the application’s requirements.
