8.6.2
EEARH and EEARL – EEPROM Address Register Atmel
ATmega325A/325PA/3250A/3250PA/625A/645P/6450A/6450P
Bits 15:11 – Reserved
These bits are reserved bits in the
ATmega325A/325PA/3250A/3250PA/645A/645P/6450A/6450P and will always read as zero.
Bits 10:0 – EEAR10:0: EEPROM Address
The EEPROM Address Registers – EEARH and EEARL specify the EEPROM address in the 1/2K bytes EEPROM
space. The EEPROM data bytes are addressed linearly between 0 and 1023/2047. The initial value of EEAR is
undefined. A proper value must be written before the EEPROM may be accessed.
Note:
1. EEAR10 is only valid for ATmega645A/ATmega645P/ATmega6450A/ATmega6450P.
8.6.3
EEDR – EEPROM Data Register
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.
8.6.4
EECR – EEPROM Control Register
Bits 7:4 – Reserved
These bits are reserved and will always read as zero.
Bit 3 – EERIE: EEPROM Ready Interrupt Enable
Writing EERIE to one enables the EEPROM Ready Interrupt if the I bit in SREG is set. Writing EERIE to zero dis-
ables the interrupt. The EEPROM Ready interrupt generates a constant interrupt when EEWE is cleared.
Bit 2 – EEMWE: EEPROM Master Write Enable
The EEMWE bit determines whether setting EEWE to one causes the EEPROM to be written. When EEMWE is
set, setting EEWE within four clock cycles will write data to the EEPROM at the selected address. If EEMWE is
