It is used and gives the "old" / last state from the pin.

See above :-)

I have not looked inside the newer devices but it is maybe necessary to 
write a timer class from scratch.

A long time ago I thought that some more generic classes and inheritance 
could solve many problems. But after looking in the details this plan 
was knocked out. To have to many switch/if inside the class for 
specialization costs to much runtime I think.

But I have actually no experience with the newer avr's so it is up to 
you to make a more general design for the newer devices.

Thanks
