/** \defgroup util_delay <util/delay.h>: Convenience functions for busy-wait delay loops
    \code
    #define F_CPU 1000000UL  // 1 MHz
    //#define F_CPU 14.7456E6
    #include <util/delay.h>
    \endcode

    \note As an alternative method, it is possible to pass the
    F_CPU macro down to the compiler from the Makefile.
    Obviously, in that case, no \c \#define statement should be
    used.

    The functions in this header file are wrappers around the basic
    busy-wait functions from <util/delay_basic.h>.  They are meant as
    convenience functions where actual time values can be specified
    rather than a number of cycles to wait for.  The idea behind is
    that compile-time constant expressions will be eliminated by
    compiler optimization so floating-point expressions can be used
    to calculate the number of delay cycles needed based on the CPU
    frequency passed by the macro F_CPU.

    \note In order for these functions to work as intended, compiler
    optimizations <em>must</em> be enabled, and the delay time
    <em>must</em> be an expression that is a known constant at
    compile-time.  If these requirements are not met, the resulting
    delay will be much longer (and basically unpredictable), and
    applications that otherwise do not use floating-point calculations
    will experience severe code bloat by the floating-point library
    routines linked into the application.

    The functions available allow the specification of microsecond, and
    millisecond delays directly, using the application-supplied macro
    F_CPU as the CPU clock frequency (in Hertz).
