24# make all = Make software.
25#
26# make clean = Clean out built project files.
27#
28# make coff = Convert ELF to AVR COFF.
29#
30# make extcoff = Convert ELF to AVR Extended COFF.
31#
32# make program = Download the hex file to the device, using avrdude.
33#                Please customize the avrdude settings below first!
34#
35# make doxygen = Generate DoxyGen documentation for the project (must have
36#                DoxyGen installed)
37#
38# make debug = Start either simulavr or avarice as specified for debugging,
39#              with avr-gdb or avr-insight as the front end for debugging.
40#
41# make filename.s = Just compile filename.c into the assembler code only.
42#
43# make filename.i = Create a preprocessed source file for use in submitting
44#                   bug reports to the GCC project.

71#     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
72#     automatically to create a 32-bit value in your source code.
73#
74#     This will be an integer division of F_CLOCK below, as it is sourced by
75#     F_CLOCK after it has run through any CPU prescalers. Note that this value
76#     does not *change* the processor frequency - it should merely be updated to
77#     reflect the processor speed set externally so that the code can use accurate

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