ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P [DATASHEET]
8285E–AVR–02/2013
Figure 7-2 shows the structure of the 32 general purpose working registers in the CPU.
Figure 7-2.
AVR CPU general purpose working registers.
Most of the instructions operating on the Register File have direct access to all registers, and most of them are sin-
gle cycle instructions.
As shown in Figure 7-2, each register is also assigned a data memory address, mapping them directly into the first
32 locations of the user Data Space. Although not being physically implemented as SRAM locations, this memory
organization provides great flexibility in access of the registers, as the X-, Y- and Z-pointer registers can be set to
index any register in the file.
7.5.1
The X-register, Y-register and Z-register
The registers R26...R31 have some added functions to their general purpose usage. These registers are 16-bit
address pointers for indirect addressing of the data space. The three indirect address registers X, Y and Z are
defined as described in Figure 7-3.
Figure 7-3.
The X-, Y- and Z-registers.
In the different addressing modes these address registers have functions as fixed displacement, automatic incre-
ment, and automatic decrement (see the instruction set reference for details).
7.6
Stack Pointer
The Stack is mainly used for storing temporary data, for storing local variables and for storing return addresses
after interrupts and subroutine calls. Note that the Stack is implemented as growing from higher to lower memory
locations. The Stack Pointer Register always points to the top of the Stack. The Stack Pointer points to the data
