# This will define a symbol, F_USB, in all source code files equal to the

|
# input clock frequency (before any prescaling is performed) in Hz. This value may
|
|
# differ from F_CPU if prescaling is used on the latter, and is required as the
|
|
# raw input clock is fed directly to the PLL sections of the AVR for high speed
|
|
# clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
|

# at the end, this will be done automatically to create a 32-bit value in your

# source code.

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