  4. # This will define a symbol, F_CPU, in all source code files equal to the
  5. # processor frequency in Hz. You can then use this symbol in your source code to
  6. # calculate timings. Do NOT tack on a 'UL' at the end, this will be done
  7. # automatically to create a 32-bit value in your source code.

  9. # This will be an integer division of F_USB below, as it is sourced by
  10. # F_USB after it has run through any CPU prescalers. Note that this value
  11. # does not *change* the processor frequency - it should merely be updated to
  12. # reflect the processor speed set externally so that the code can use accurate
  13. # software delays.

  22. # input clock frequency (before any prescaling is performed) in Hz. This value may
  23. # differ from F_CPU if prescaling is used on the latter, and is required as the
  24. # raw input clock is fed directly to the PLL sections of the AVR for high speed
  25. # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
  26. # at the end, this will be done automatically to create a 32-bit value in your
  27. # source code.

  30. # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
