14 # F_USB after it has run through any CPU prescalers. Note that this value

16 # reflect the processor speed set externally so that the code can use accurate
23 # Target architecture (see library "Board Types" documentation).

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

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