SRAM data memory
Figure 8-2 shows how the ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P SRAM
Memory is organized.
The ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P is a complex microcontroller
with more peripheral units than can be supported within the 64 location reserved in the Opcode
for the IN and OUT instructions. For the Extended I/O space from $060 - $FF in SRAM, only the
ST/STS/STD and LD/LDS/LDD instructions can be used.
The first 4,352 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 4,096 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.
