The I/O space definition of the Atmel
page
All Atmel ATA6612/ATA6613 I/Os and peripherals are placed in the I/O space. All I/O loca-
tions 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 instruc-
tions. 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 Atmel ATA6612/ATA6613 is a complex microcontroller with more peripheral
units than can be supported within the 64 location reserved in Opcode for the IN and OUT
instructions. 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 AVR
instructions will only operate on the specified bit, and can therefore be used on registers con-
taining 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.
The Atmel ATA6612/ATA6613 contains three General Purpose I/O Registers. These registers
can be used for storing any information, and they are particularly useful for storing global vari-
ables 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.
