I'm having a difficult time using PORT E. In reading the Atmel 128 documentation, it appears for the most part the it should act like ports D and B, which I use all I/Os. The only?Port?pins (I/Os)?I appear to be able to control are 4, 6 and 7.



I've tried changing the alternate pin functions, but can't figure out how to access them. For example, the Atmel manual indicates settings in PVOExn where "x" is Port designation (B, D, E) and n is the I/O, but I get a compiler error when I try to use something like "PVOEE1," for example.



I use pins 6 and 7 with no problem, and I know 0 and 1 are used by the serial port. I really need two more, but I don't any confidence that I have figured pin 4.
