  35 # make doxygen = Generate DoxyGen documentation for the project (must have

  64 # Processor frequency.
  65 #     This will define a symbol, F_CPU, in all source code files equal to the
  66 #     processor frequency in Hz. You can then use this symbol in your source code to
  67 #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
  68 #     automatically to create a 32-bit value in your source code.
  69 #
  70 #     This will be an integer division of F_USB below, as it is sourced by
  71 #     F_USB after it has run through any CPU prescalers. Note that this value
  72 #     does not *change* the processor frequency - it should merely be updated to
  73 #     reflect the processor speed set externally so that the code can use accurate

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