The X-, Y-, and Z-registers
In the different addressing modes these address registers have functions as fixed displacement,
automatic increment, and automatic decrement (see the instruction set reference for details).
4.6
Stack Pointer
The Stack is mainly used for storing temporary data, local variables and return addresses for
interrupts and subroutine calls. The Stack Pointer Register always points to the top of the Stack,
in the data SRAM Stack area where the subroutine and interrupt stacks are located.
The Stack in the data SRAM must be defined by the program before any subroutine calls are
executed or interrupts are enabled. The Stack Pointer must be set to point above start of the
SRAM (see Figure 5-2 on page 16). The initial Stack Pointer value equals the last address of the
internal SRAM.
Note that the Stack is implemented as growing from higher to lower memory locations. This
means a Stack PUSH command decreases the Stack Pointer. See Table 4-1.
The AVR Stack Pointer is implemented as two 8-bit registers in the I/O space. The number of
bits actually used is implementation dependent.
Note that the data space in some implementations of the AVR architecture is so small that only
SPL is needed. In this case, the SPH Register will not be present.
