/**
 * @file
 * This file contains definitions for characteristics of the target CPU and
 * compiler, including primitive data types and endianness.
 *
 * This file defines the byte order and primitive data types for various
 * CPU families. The preprocessor symbol 'CPU' must be defined to be an
 * appropriate value or this header will generate a compile-time error.
 *
 * @note The documentation for this header file uses the x86 family of processors
 * as an illustrative example for CPU/compiler-dependent data type definitions.
 * Go to the source code of this header file to see the details of primitive type
 * definitions for each platform.

 * Additional information is available in the @ref data_types_docpage section.
