Detailed Description

Common Symbols and Define Undefined Registers.

This purpose of this header is to define registers that have not been previously defined in the individual device IO header files, and to define other symbols that are common across AVR device families.

This file is designed to be included in <avr/io.h> after the individual device IO header files, and after <avr/sfr_defs.h>
