[avr-libc-dev] [bug #18964] USART definitions *wrong* in iocanxx.h

[Eric Weddington]

Update of bug #18964 (project avr-libc):

                  Status:                    None => Invalid                
             Assigned to:                    None => arcanum                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

>From the avr-libc user manual:

"Starting with avr-libc version 1.4.0, a second style of interrupt vector
names has been added, where a short phrase for the vector description is
followed by _vect. The short phrase matches the vector name as described in
the datasheet of the respective device (and in Atmel's XML files), with
spaces replaced by an underscore and other non-alphanumeric characters
dropped. Using the suffix _vect is intented to improve portability to other C
compilers available for the AVR that use a similar naming convention.

The historical naming style might become deprecated in a future release, so
it is not recommended for new projects."

Note the last sentence. The iocanxx.h has the correct naming with the
"USART*" prefix. The vector names that start with "SIG*" should not be used
anymore.
