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...

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!
