  72 # Processor frequency.
  73 #     This will define a symbol, F_CPU, in all source code files equal to the
  74 #     processor frequency. You can then use this symbol in your source code to
  75 #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
  76 #     automatically to create a 32-bit value in your source code.
  77 #     Typical values are:
  78 #         F_CPU =  1000000
  79 #         F_CPU =  1843200
  80 #         F_CPU =  2000000
  81 #         F_CPU =  3686400
  82 #         F_CPU =  4000000
  83 #         F_CPU =  7372800
  84 #         F_CPU =  8000000
  85 #         F_CPU = 11059200
  86 #         F_CPU = 14745600
  87 #         F_CPU = 16000000
  88 #         F_CPU = 18432000

  90 F_CPU = 8000000

  92
  93 # Input clock frequency.
  94 #     This will define a symbol, F_CLOCK, in all source code files equal to the
  95 #     input clock frequency (before any prescaling is performed). This value may
  96 #     differ from F_CPU if prescaling is used on the latter, and is required as the
  97 #     raw input clock is fed directly to the PLL sections of the AVR for high speed
  98 #     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
  99 #     at the end, this will be done automatically to create a 32-bit value in your
 100 #     source code.
 101 #
 102 #     If no clock division is performed on the input clock inside the AVR (via the
 103 #     CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
