You have to use what _realy_ is used on your hardware. So check with your hardware designers, if they soldered a 33.0 MHz oscillator or a 33.333 or... > It shouldnt concern too much, but seeing that something like > 33,333,000 is even used, couldnt help wonder what should it really > be.. Yes, it should concern. Keep in mind, that a change from 33.0 to 33.3 is 1% and this could result in the system clock running 1% slower (or faster) as desired! Best regards, Stefan
