 -i delay

    For bitbang-type programmers, delay for approximately delay 
microseconds between each bit state change. If the host system is very 
fast, or the target runs off a slow clock (like a 32 kHz crystal, or the 
128 kHz internal RC oscillator), this can become necessary to satisfy 
the requirement that the ISP clock frequency must not be higher than 1/4 
of the CPU clock frequency. This is implemented as a spin-loop delay to 
allow even for very short delays. On Unix-style operating systems, the 
spin loop is initially calibrated against a system timer, so the number 
of microseconds might be rather realistic, assuming a constant system 
load while AVRDUDE is running. On Win32 operating systems, a 
preconfigured number of cycles per microsecond is assumed that might be 
off a bit for very fast or very slow machines.
