ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P [DATASHEET]

I/O memory
The I/O space definition is shown in ”Register Summary” on page 807.
All Atmel ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P I/Os and peripherals are
placed in the I/O space. All I/O locations may be accessed by the LD/LDS/LDD and ST/STS/STD instructions,
transferring data between the 32 general purpose working registers and the I/O space. I/O Registers within the
address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the
value of single bits can be checked by using the SBIS and SBIC instructions. Refer to the instruction set section for
more details. 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
addresses.
The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P is a complex microcontroller with
more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instruc-
tions. For the Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions
can be used.
For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory
addresses should never be written.
Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI
and SBI instructions will only operate on the specified bit, and can therefore be used on registers containing such
Status Flags. The CBI and SBI instructions work with registers 0x00 to 0x1F only.
The I/O and peripherals control registers are explained in later sections.
8.5
General purpose I/O registers
The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P contains three General Purpose
I/O Registers. These registers can be used for storing any information, and they are particularly useful for storing
global variables and Status Flags. General Purpose I/O Registers within the address range 0x00 - 0x1F are directly
bit-accessible using the SBI, CBI, SBIS, and SBIC instructions.

Register description
8.6.1
EEARH and EEARL – EEPROM Address Register ATmega165A/ATmega165PA
Bits 15:9 – Reserved
These bits are reserved and will always read as zero.
Bits 8:0 – EEAR8:0: EEPROM Address
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.
