/*! \file *********************************************************************
*
* \brief XMEGA Watchdog driver header file.
*
* This file contains the function prototypes and enumerator definitions
* for various configuration parameters for the XMEGA Watchdog driver.
*
* The driver is not intended for size and/or speed critical code, since
* most functions are just a few lines of code, and the function call
* overhead would decrease code performance. The driver is intended for
* rapid prototyping and documentation purposes for getting started with
* the XMEGA Watchdog module.
*
* For size and/or speed critical code, it is recommended to copy the
* function contents directly into your application instead of making
* a function call. Another way is to define all the functions as macros.
*
* \par Application note:
* AVR1310: Using the XMEGA Watchdog
*
* \par Documentation
* For comprehensive code documentation, supported compilers, compiler
* settings and supported devices see readme.html
