 XMEGA TWI slave driver source file.
 This file contains the function implementations the XMEGA TWI slave

 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 TWI slave 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.

 Several functions use the following construct:
     "some_register = ... | (some_parameter ? SOME_BIT_bm : 0) | ..."
 Although the use of the ternary operator ( if ? then : else ) is
 discouraged, in some occasions the operator makes it possible to write
 pretty clean and neat code. In this driver, the construct is used to
 set or not set a configuration bit based on a boolean input parameter,
 such as the "some_parameter" in the example above.
