* The first 512 bytes (boot sector) of an attached disk's memory will be dumped
* out of the serial port in HEX and ASCII form when it is attached to the AT90USB1287

# make dfu = Download the hex file to the device, using dfu-programmer (must

# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. 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.
# Typical values are:
# F_CPU = 1000000
# F_CPU = 1843200
# F_CPU = 2000000
# F_CPU = 3686400
# F_CPU = 4000000

# F_CPU = 8000000

# F_CPU = 18432000

# This will define a symbol, F_CLOCK, in all source code files equal to the
# input clock frequency (before any prescaling is performed). 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.
