Corresponding source code
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...
