Figure 9
The lower 224 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, and the next 128 locations address the internal data
SRAM.
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, and the 128 bytes of internal data
SRAM in the ATtiny2313 are all accessible through all these addressing modes. The Register
File is described in
Figure 9. Data Memory Map
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
shows how the ATtiny2313 SRAM Memory is organized.
