The Stack Pointer
AVR32
rations of shadowed registers. This allows for maximum flexibility in targeting the processor for
different application, see
Figure 2-4.
Three different shadowing schemes are offered, small, half and full, ranging from no general
registers shadowed to all general registers shadowed, see
Figure 2-5.
Since the Stack Pointer (SP) is located in the register file, it can be addressed as an ordinary
register. This simplifies allocation and access of local variables and parameters. The Stack
Pointer is also used implicitly by several instructions.
The system modes have a shadowed stack pointer different from the application mode stack
pointer. This allows having a separate system stack.
