twis.h File Reference

XMEGA TWI slave driver header file.

 This file contains the function prototypes and enumerator definitions
 for various configuration parameters for the XMEGA TWI slave 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 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.
