8.6 General Purpose I/O Registers
8.6.1 GPIOR0 – General Purpose IO Register 0
8.6.2 GPIOR1 – General Purpose IO Register 1
8.6.3 GPIOR2 – General Purpose I/O Register 2
8266B-MCU Wireless-03/11
0x20 must be added to these addresses. The ATmega128RFA1 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 – 0x1FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be
used.
For compatibility with future devices, reserved bits may not be modified. Reserved
registers and 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 control registers of I/O and peripherals are explained in later sections.
The ATmega128RFA1 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.
The three General Purpose I/O Registers can be used for storing any information.

The three General Purpose I/O Registers can be used for storing any information.
