Configuration File
The configuration file format matches the Metrowerks CodeWarrior interface. The file is simply a test file
describing how programmers should communicate with the device, and how the device is physically
constructed. The file allows a comment (‘#’) character. The following options are allowed in the
configuration file. Their behavior may be different for the Metrowerks CodeWarrior tool, especially for
options ignored by this tool.
