# 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
+# 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.
-# Typical values are:
-# F_CPU = 1000000
-# F_CPU = 1843200
-# F_CPU = 2000000
-# F_CPU = 3686400
-# F_CPU = 4000000
-# F_CPU = 7372800
-# F_CPU = 8000000
-# F_CPU = 11059200
-# F_CPU = 14745600
-# F_CPU = 16000000
-# F_CPU = 18432000
-# F_CPU = 20000000

+# This will be an integer division of F_CLOCK below, as it is sourced by
+# F_CLOCK 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.
F_CPU = 16000000
# Input clock frequency.
# 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
+# 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'
#
# 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.
