  35               	
  36               	    This header file includes the apropriate IO definitions for the
  37               	    device that has been specified by the <tt>-mmcu=</tt> compiler
  38               	    command-line switch.  This is done by diverting to the appropriate
  39               	    file <tt>&lt;avr/io</tt><em>XXXX</em><tt>.h&gt;</tt> which should
  40               	    never be included directly.  Some register names common to all
  41               	    AVR devices are defined directly within <tt>&lt;avr/io.h&gt;</tt>,
  42               	    but most of the details come from the respective include file.
  43               	
  44               	    Note that this file always includes
  45               	    \code #include <avr/sfr_defs.h> \endcode
  46               	    See \ref avr_sfr for the details.
  47               	
  48               	    Included are definitions of the IO register set and their
  49               	    respective bit values as specified in the Atmel documentation.
  50               	    Note that Atmel is not very consistent in its naming conventions,
  51               	    so even identical functions sometimes get different names on
  52               	    different devices.
  53               	
  54               	    Also included are the specific names useable for interrupt
  55               	    function definitions as documented
  56               	    \ref avr_signames "here".
  57               	
  58               	    Finally, the following macros are defined:
  59               	
  60               	    - \b RAMEND
  61               	    <br>
  62               	    A constant describing the last on-chip RAM location.
  63               	    <br>
  64               	    - \b XRAMEND
  65               	    <br>
  66               	    A constant describing the last possible location in RAM.
  67               	    This is equal to RAMEND for devices that do not allow for
  68               	    external RAM.
  69               	    <br>
  70               	    - \b E2END
  71               	    <br>
  72               	    A constant describing the address of the last EEPROM cell.
  73               	    <br>
  74               	    - \b FLASHEND
  75               	    <br>
  76               	    A constant describing the last byte address in flash ROM.
  77               	    <br>
  78               	    - \b SPM_PAGESIZE

  80               	    For devices with bootloader support, the flash pagesize

  41               	   The \c <avr/sfr_defs.h> file is included by all of the \c <avr/ioXXXX.h>
  42               	   files, which use macros defined here to make the special function register
  43               	   definitions look like C variables or simple constants, depending on the
  44               	   <tt>_SFR_ASM_COMPAT</tt> define.  Some examples from \c <avr/iom128.h> to
  45               	   show how to define such macros:
  46               	
  47               	\code
  48               	#define PORTA _SFR_IO8(0x1b)
  49               	#define TCNT1 _SFR_IO16(0x2c)
  50               	#define PORTF _SFR_MEM8(0x61)
  51               	#define TCNT3 _SFR_MEM16(0x88)
  52               	\endcode
  53               	
  54               	   If \c _SFR_ASM_COMPAT is not defined, C programs can use names like
  55               	   <tt>PORTA</tt> directly in C expressions (also on the left side of
  56               	   assignment operators) and GCC will do the right thing (use short I/O
  57               	   instructions if possible).  The \c __SFR_OFFSET definition is not used in
  58               	   any way in this case.
  59               	
  60               	   Define \c _SFR_ASM_COMPAT as 1 to make these names work as simple constants
  61               	   (addresses of the I/O registers).  This is necessary when included in
  62               	   preprocessed assembler (*.S) source files, so it is done automatically if
  63               	   \c __ASSEMBLER__ is defined.  By default, all addresses are defined as if
  64               	   they were memory addresses (used in \c lds/sts instructions).  To use these
  65               	   addresses in \c in/out instructions, you must subtract 0x20 from them.
  66               	
  67               	   For more backwards compatibility, insert the following at the start of your
  68               	   old assembler source file:
  69               	
  70               	\code
  71               	#define __SFR_OFFSET 0
  72               	\endcode
  73               	
  74               	   This automatically subtracts 0x20 from I/O space addresses, but it's a
  75               	   hack, so it is recommended to change your source: wrap such addresses in
  76               	   macros defined here, as shown below.  After this is done, the
  77               	   <tt>__SFR_OFFSET</tt> definition is no longer necessary and can be removed.
  78               	
  79               	   Real example - this code could be used in a boot loader that is portable
  80               	   between devices with \c SPMCR at different addresses.
