Re: [avr-gcc-list] a question about atmega128 io port

[David Breeze]

Hi,
These are signals which are internal to the 128 and are concerned with 
accessing the various areas of a port bit.  (Write data, read data set port 
direction etc.)  The definition of the signals is given immediately below the 
diagram.

HTH.
