Some AVR chips ship with a "clock prescaler" that causes the
chip to run at 1/8th speed. Enable this setting to clear the
prescaler field at startup which will cause the chip to run
without a clock divisor.

help
Compile the code to run on simulavr software emulation
instead of for real hardware. This disables support for "U2X
baud" mode and for the watchdog timer which are not supported
on simulavr.
If unsure, select "N".
