_______________________________________________________
Details:
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.)
