compatibility with AT90CAN128

[JerryKomor]

I used the library on other controllers Atmega328, ATtiny85 and few others.
I'm working on new project and I need to have 11 buttons and having problems with the library compatibility with the processor. Using MCUdude MEGAcore library for the processor.
I have tried direct reading and writing to the ports and it works.

Any one had used the library with this micro, or maybe someone can see issues with my code. had it also shrunk down to 2 buttions
