# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency in Hz. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
#
# This will be an integer division of F_USB below, as it is sourced by
# F_USB after it has run through any CPU prescalers. Note that this value
# does not *change* the processor frequency - it should merely be updated to
# reflect the processor speed set externally so that the code can use accurate
# software delays.

# Input clock frequency.
# 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.
#
# If no clock division is performed on the input clock inside the AVR (via the
# CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
