    What's wrong?
    You left out that vital bit of information (the 1:128 prescale).

    So, it's happening every 1ms instead of 10ms?
    Are you sure you're correctly clearing/re-enabling the correct interrupt after you are done processing the interrupt...or is the interrupt sequence 'jumping right back into itself' after you are done processing it?
