IR transmission was pretty tough to get at. Carrier frequency was the
final key - there are no crystals to create the IR carrier, so the
processor has to provide it.
It turns out that 8-bit t1 output is used for just that purpose. Guess
I'll have to rewrite my scheduler to use the 16bit timer now. Anyway,
native IR transmission works now.
