Since this is interrupt driven for the capture, then the serial
routine is killing the counters by missing them. I would move the
currTC = T0CR2 into the IRQ routien and make it a volatile global so
that you can read it and clear it off. I would also do the prevTC =
currTC in the interrupt routine as well.
