    # Processor frequency.
    #     This will define a symbol, F_CPU, in all source code files equal to the 
    #     processor frequency in Hz. You can then use this symbol in your source code to 
    #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
    #     automatically to create a 32-bit value in your source code.
    #
    #     This will be an integer division of F_CLOCK below, as it is sourced by
    #     F_CLOCK after it has run through any CPU prescalers. Note that this value
    #     does not *change* the processor frequency - it should merely be updated to
    #     reflect the processor speed set externally so that the code can use accurate
    #     software delays.

    # Input clock frequency.
    #     This will define a symbol, F_CLOCK, in all source code files equal to the 
    #     input clock frequency (before any prescaling is performed) in Hz. This value may
    #     differ from F_CPU if prescaling is used on the latter, and is required as the
    #     raw input clock is fed directly to the PLL sections of the AVR for high speed
    #     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
    #     at the end, this will be done automatically to create a 32-bit value in your
    #     source code.
    #
    #     If no clock division is performed on the input clock inside the AVR (via the
