IF there's any reason for this delay, it is to allow for some clock generating 
PLL to stabilize before we enable any function relying on stable clock (maybe 
A/D-probe? PWM? ''enable_irq(IRQ_ADC); enable_irq(IRQ_TC)'').
However I do not know the CPU manual by heart, so I can't tell whether this 
applies here at all.
