I've this on HEAD and 1.0 branch.

The PORTxn changes are really a separate issue and are being handled.

The 09/02 version of the datasheet still has UPEn. I see no mention of PEn in the UCSRnA register summary. I'm going to simply replace PEn with UPEn instead of adding UPEn and making PEn an alias.

Now the PORTE part brings up another issue. The usage is not consistant in this header file. All other port pins are defined like PAn while PORTE is PORTEn. The datasheet register summary shows them all as PORTxn. I'd prefer to just have all the headers use Pxn regardless of what the datasheets say, but that doesn't seem to be the concensus of the developers.

In definitions for UCSR0A: bit 2 is defined as PE0, this should be UPE0. In definitions for UCSR1A: bit 2 is defined as PE1, this should be UPE1. This according to datasheet for Atmega162(V) rev: 2513E-AVR-09/03

I guess this is the reson why PORTE bits are defined as PORTE0, PORTE1.... instead of PE0, PE1.. as would be normal.

I am usign WinAVR-20030913
