+# 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
+# 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.
