* Since STICK is constantly updating, we have to access it carefully.

* The sequence we use to read is:
* 1) read low
* 2) read high
* 3) read low again, if it rolled over increment high by 1
* 1) read high
* 2) read low
* 3) read high again, if it rolled re-read both low and high again.
*
* Writing STICK safely is also tricky:
* 1) write low to zero
