The EEPROM Address Registers – EEARH and EEARL
The EEPROM Data Register – EEDR
The EEPROM Control Register – EECR
• Bits 15.11 – Reserved Bits
These bits are reserved bits in the ATmega16/32/64/M1/C1 and will always read as zero.
• Bits 9..0 – EEAR10..0: EEPROM Address
The EEPROM Address Registers – EEARH and EEARL specify the EEPROM address in the
512/1024/2048 bytes EEPROM space. The EEPROM data bytes are addressed linearly
between 0 and 511/1023/2047. The initial value of EEAR is undefined. A proper value must be
written before the EEPROM may be accessed.
• Bits 7..0 – EEDR7.0: EEPROM Data
For the EEPROM write operation, the EEDR Register contains the data to be written to the
EEPROM in the address given by the EEAR Register. For the EEPROM read operation, the
EEDR contains the data read out from the EEPROM at the address given by EEAR.
• Bits 7..6 – Reserved Bits
These bits are reserved bits in the ATmega16/32/64/M1/C1 and will always read as zero.
• Bits 5..4 – EEPM1 and EEPM0: EEPROM Programming Mode Bits
The EEPROM Programming mode bit setting defines which programming action that will be
triggered when writing EEWE. It is possible to program data in one atomic operation (erase
the old value and program the new value) or to split the Erase and Write operations in two dif-
ferent operations. The Programming times for the different modes are shown in
