Instead of reflashing the whole storage, we use a designated area in the second storage block, where we mark each PIN failure by a single zero bit. This is because one can set bits in flash to zero but not to one. If the PIN was entered successfully the whole word is set to zero and the next word stores the new PIN failure counter.
