BP>Some thing to do with sign extension after 32767? if the timer routine takes in signed argument values, then yes, it could be. If you cast from unsigned int (0-65535) to a signed int (-32768 --32767) the values higher than 32767 will not correspond (the first bit of the number either means a sign or 32768) That is why 50000 turns into -17232.
