/** \defgroup avr_assert <assert.h>: Diagnostics
\code #include <assert.h> \endcode
This header file defines a debugging aid.
As there is no standard error output stream available for many
applications using this library, the generation of a printable
error message is not enabled by default. These messages will
only be generated if the application defines the macro
\code __ASSERT_USE_STDERR \endcode
before including the \c <assert.h> header file. By default,
only abort() will be called to halt the application.

/**
* \def assert
* \param expression Expression to test for.
*
* The assert() macro tests the given expression and if it is false,
* the calling process is terminated. A diagnostic message is written
* to stderr and the function abort() is called, effectively
* terminating the program.
*
* If expression is true, the assert() macro does nothing.
*
* The assert() macro may be removed at compile time by defining
* NDEBUG as a macro (e.g., by using the compiler option -DNDEBUG).
