-#     processor frequency in Hz. You can then use this symbol in your source code to

-#     This will be an integer division of F_USB below, as it is sourced by
-#     F_USB 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

-# Input clock frequency.
-#     This will define a symbol, F_USB, 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
