EEARL – EEPROM Address Register
EEDR – EEPROM Data Register
EECR – EEPROM Control Register
• Bit 7 – EEAR7: EEPROM Address
This is the most significant EEPROM address bit of ATtiny461A. In devices with less EEPROM,
i.e. ATtiny261A, this bit is reserved and will always read zero. The initial value of the EEPROM
Address Register (EEAR) is undefined and a proper value must therefore be written before the
EEPROM is accessed.
• Bits 6:0 – EEAR6:0: EEPROM Address
These are the (low) bits of the EEPROM Address Register. The EEPROM data bytes are
addressed linearly in the range 0
proper value must be therefore 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.
• Bit 7 – Res: Reserved Bit
This bit is reserved for future use and will always read zero. For compatibility with future AVR
devices, always write this bit to zero. After reading, mask out this bit.
• Bit 6 – Res: Reserved Bit
This bit is reserved and will always read as zero.
• Bits 5, 4 – EEPM1 and EEPM0: EEPROM Programming Mode Bits
The EEPROM Programming mode bits setting defines which programming action that will be
triggered when writing EEPE. It is possible to program data in one atomic operation (erase the
