  76 # Processor frequency.

  79 #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
  80 #     automatically to create a 32-bit value in your source code.
  81 #
  82 #     This will be an integer division of F_CLOCK below, as it is sourced by
  83 #     F_CLOCK after it has run through any CPU prescalers. Note that this value
  84 #     does not *change* the processor frequency - it should merely be updated to
  85 #     reflect the processor speed set externally so that the code can use accurate

  90 # Input clock frequency.
  91 #     This will define a symbol, F_USB, in all source code files equal to the
  92 #     input clock frequency (before any prescaling is performed) in Hz. This value may
  93 #     differ from F_CPU if prescaling is used on the latter, and is required as the
  94 #     raw input clock is fed directly to the PLL sections of the AVR for high speed
  95 #     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
  96 #     at the end, this will be done automatically to create a 32-bit value in your
  97 #     source code.
