The Data Memory consist of the I/O Memory, EEPROM and SRAM memories, all within one lin-
ear address space, see
devices in the family is identical and with empty, reserved memory space for smaller devices.
All peripherals and modules are addressable through I/O memory locations in the data memory
space. All I/O memory locations can be accessed by the Load (LD/LDS/LDD) and Store
(ST/STS/STD) instructions, transferring data between the 32 general purpose registers in the
CPU and the I/O Memory.
The IN and OUT instructions can address I/O memory locations in the range 0x00 - 0x3F
directly.
I/O registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and
CBI instructions. The value of single bits can be checked by using the SBIS and SBIC instruc-
tions on these registers.
The I/O memory address for all peripherals and modules in XMEGA A4 is shown in the
eral Module Address Map” on page
The XMEGA A4 devices have internal SRAM memory for data storage.
