/** \defgroup avr_eeprom <avr/eeprom.h>: EEPROM handling
    \code #include <avr/eeprom.h> \endcode

    This header file declares the interface to some simple library
    routines suitable for handling the data EEPROM contained in the
    AVR microcontrollers.  The implementation uses a simple polled
    mode interface.  Applications that require interrupt-controlled
    EEPROM access to ensure that no time will be wasted in spinloops
    will have to deploy their own implementation.

    \par Notes:

    - In addition to the write functions there is a set of update ones.
    This functions read each byte first and skip the burning if the
    old value is the same with new.  The scaning direction is from
    high address to low, to obtain quick return in common cases.

    - All of the read/write functions first make sure the EEPROM is
    ready to be accessed.  Since this may cause long delays if a
    write operation is still pending, time-critical applications
    should first poll the EEPROM e. g. using eeprom_is_ready() before
    attempting any actual I/O.  But this functions are not wait until
    SELFPRGEN in SPMCSR becomes zero.  Do this manually, if your
    softwate contains the Flash burning.

    - As these functions modify IO registers, they are known to be
    non-reentrant.  If any of these functions are used from both,
    standard and interrupt context, the applications must ensure
    proper protection (e.g. by disabling interrupts before accessing
    them).

    - All write functions force erase_and_write programming mode.
    
    - For Xmega the EEPROM start address is 0, like other architectures.
    The reading functions add the 0x2000 value to use EEPROM mapping into
    data space.
