  76 # Processor frequency.

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

  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
