hi !

the low value ceramic cap (near the ic) is used to reset the ic (cuz when you power up everything, small caps like those act as a little short circuit (only for some mS), therefore, it causes the ic to reset).... and the big caps near the supply is used to minimize dv/dt... as you probably know, caps are made to do so, therefore, higher is the cap (near the source), less dv you will have in your circuit (witch is a good thing...)

hope this was helpful
