SRAM Data Memory
Figure 3-2
shows how the ATtiny87/167 SRAM Memory is organized.
The ATtiny87/167 is a complex microcontroller with more peripheral units than can be sup-
ported within the 64 locations reserved in the Opcode for the IN and OUT instructions. For the
Extended I/O space in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be
used.
The 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 160 locations of Extended I/O memory, and the
next locations address the internal data SRAM (see “ISRAM size” in
Table 3-1 on page
15).
The five different addressing modes for the Data memory cover: Direct, Indirect with Displace-
ment, Indirect, 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, 160 Extended I/O Registers and
the internal data SRAM in the ATtiny87/167 are all accessible through all these addressing
modes. The Register File is described in
“General Purpose Register File” on page
10.
