1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these
3. Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI
4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
5. Only valid for the Atmel ATmega88A/88PA/168A/168PA/328/328P.

registers, the value of single bits can be checked by using the SBIS and SBIC instructions.
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.
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The Atmel
ATmega48PA/88PA/168PA 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.
