Register Description
EEARH – EEPROM Address Register
EEARL – EEPROM Address Register
EEDR – EEPROM Data Register
EECR – EEPROM Control Register
• Bits 7..1 – Res: Reserved Bits
These bits are reserved bits in the Atmel
• Bit 0 – EEAR8: EEPROM Address
This bit is reserved bit and will always read as zero. The initial value of EEAR is undefined. A
proper value must be written before the EEPROM may be accessed.
• Bits 7..0 – EEAR7..0: EEPROM Address
The EEPROM Address Register – EEARL – specifies the EEPROM address. The EEPROM
data bytes are addressed linearly between 0 and 256. 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.
