Summary:  iomx8.h ATmega48 eeprom EEAR  EEARH 

Original Submission:  The header "iomx8.h" don't work for the eeprom of the 
ATmega48 because of:
 
#if defined (__AVR_ATmega88__) || defined (__AVR_ATmega168__)
#  define EEAR  _SFR_IO16 (0x21)
#  define EEARH _SFR_IO8 (0x22)
#endif

The ATmega48 has only 256 byte eeprom, but despite of this for programming or 
reading, one has to write a zero to EEARH or a uint16_t to EEAR...
 
Maybe this will be correctet in a newer version...
