29 # This will define a symbol, F_USB, in all source code files equal to the
30 # input clock frequency (before any prescaling is performed) in Hz. This value may
31 # differ from F_CPU if prescaling is used on the latter, and is required as the
32 # raw input clock is fed directly to the PLL sections of the AVR for high speed
33 # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
