SRAM Data
Memory

Figure 9 shows how the AT90USB82/162 SRAM Memory is organized.
The AT90USB82/162 is a complex microcontroller with more peripheral units than can be sup-
ported within the 64 location reserved in the Opcode for the IN and OUT instructions. For the
Extended I/O space from $060 - $1FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instruc-
tions can be used.
The first 512 Data Memory locations address both the Register File, the I/O Memory, Extended
I/O Memory, and the internal data SRAM. The first 32 locations address the Register file, the
next 64 location the standard I/O Memory, then 416 locations of Extended I/O memory.The five
different addressing modes for the data memory cover: Direct, Indirect with Displacement, Indi-
rect, Indirect with Pre-decrement, and Indirect with Post-increment. In the Register file, registers
R26 to R31 feature the indirect addressing pointer registers.
The direct addressing reaches the entire data space.
The Indirect with Displacement mode reaches 63 address locations from the base address given
by the Y- or Z-register.
When using register indirect addressing modes with automatic pre-decrement and post-incre-
ment, the address registers X, Y, and Z are decremented or incremented.
The 32 general purpose working registers, 64 I/O registers, and the 512 bytes of internal data
SRAM in the AT90USB82/162 are all accessible through all these addressing modes. The Reg-
ister File is described in “General Purpose Register File” on page 9.
