;* Description:
;* Source file for application note AVR001 - Conditional Assembly
;* and Portability Macros.
;*
;* Defines a number of macros that makes it easier to access
;* IO registers and extended IO registers (or SRAM locations up
;* to adress $FF if applicable).
;* The macros can be used to produce code that assembles to
;* any target AVR, without considering if the accessed IO
;* registers are located in low, standard or extended IO space
