12.6.1 EEARL – The EEPROM Address Register Low
Name: EEARL
Offset: 0x1E [ID-000004d0]
Reset: 0xXX
Property: When addressing I/O Registers as data space the offset address is 0x3E
When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When
addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these offset
addresses.

Bits 7:0 – EEARn[7:0] EEPROM Address [n = 7:0]
The EEPROM Address Registers – EEARH and EEARL – specify the EEPROM address in the 512 bytes
EEPROM space. The EEPROM data bytes are addressed linearly between 0 and 511. The initial value of
EEAR is undefined. A proper value must be written before the EEPROM may be accessed.
