it's my understanding from the datasheet that the atmega32u4 doesn't have a Timer 2, so it seems like the definitions for TCCR2A, TIFR2, TCNT2, etc, should be missing from the header file.

all of those are, indeed, missing from iom32u2.h, so i think their presence in iom32u4.h must be just an oversight.

apparently timer 2 isn't mentioned in the ATmega32U4.xml part description file provided with AVR Studio, either, though i was told this at the avrfreaks forum, and don't know it firsthand.

(my version is 1.6.8-2, from ubuntu natty.)
