12 # Processor frequency.
13 # This will define a symbol, F_CPU, in all source code files equal to the
14 # processor frequency in Hz. You can then use this symbol in your source code to
15 # calculate timings. Do NOT tack on a 'UL' at the end, this will be done
16 # automatically to create a 32-bit value in your source code.
18 # This will be an integer division of F_USB below, as it is sourced by
19 # F_USB after it has run through any CPU prescalers. Note that this value
20 # does not *change* the processor frequency - it should merely be updated to
21 # reflect the processor speed set externally so that the code can use accurate
28 # Target architecture (see library "Board Types" documentation).
31 # Input clock frequency.
32 # This will define a symbol, F_USB, in all source code files equal to the
33 # input clock frequency (before any prescaling is performed) in Hz. This value may
34 # differ from F_CPU if prescaling is used on the latter, and is required as the
35 # raw input clock is fed directly to the PLL sections of the AVR for high speed
36 # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
37 # at the end, this will be done automatically to create a 32-bit value in your
40 # If no clock division is performed on the input clock inside the AVR (via the
41 # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
