Data Memory Access Times

The ATmega329/3290/649/6490 is a complex microcontroller with more peripheral units than
can be supported within the 64 locations reserved in the Opcode for the IN and OUT instruc-
tions. For the Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and
LD/LDS/LDD instructions can be used.
The lower 2304/4352 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 2048/4096 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, 160 Extended I/O Registers, and
the 2,048 bytes of internal data SRAM in the ATmega329/3290/649/6490 are all accessible
through all these addressing modes. The Register File is described in
ter File” on page
Figure 7-2.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
