Detailed Description

AVR port configuration.

This file collects all port specifications for the AVR platform and provides an overview of hardware resources in use.

Values are geared to the Ethernut reference design and can be changed by the Configurator. This program creates a file with the same name in the build tree, which replaces this placeholder.
