i thought the timer counts always down (at least all my code relies on that,
and seems to work) ?
quoting the data sheet:
"When the timer has counted thru 00000000 on the next count time an interrupt
will occur and the counter will read 11111111. After interrupt, the timer
register decrements at a divide by "1" rate of the system clock..."
so what you have to take care of is that after the timer expired, it will
run at the osc's frequency, rather than at oscfreq/64.
