* \brief
|
||||
* XMEGA USART driver source file.
|
||||
*
|
||||
* This file contains the function implementations the XMEGA interrupt
|
||||
* and polled USART 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 ADC 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.
|
||||
*
|
||||
* Some 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.
|
||||

* This file contains the function prototypes and enumerator definitions

* for various configuration parameters for the XMEGA USART 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

* the XMEGA ADC 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.
