What is stack pointer assembly?
The Stack Pointer is a special register in I/O Memory that points to space allocated in SRAM, referred to as The Stack. The Stack is used to temporarily store register values and return addresses when subroutines are called. The Stack Pointer is a 16-bit register defined in include files as SPH and SPL.
How to initialize stack pointer in assembly?
To set up the stack pointers, enter each mode with interrupts disabled, and assign the appropriate value to the stack pointer. The stack pointer value set up in the reset handler is automatically passed as a parameter to __user_initial_stackheap() by C library initialization code.
What is SPL in AVR?
SPH holds the most significant address byte, SPL the least significant. This is only true, if the AVR type has more than 256 byte SRAM. If not, SPH is undefined and must not and cannot be used.
Stack registers in x86
In 8086, the main stack register is called stack pointer - SP. The stack segment register (SS) is usually used to store information about the memory segment that stores the call stack of currently executed program. SP points to current stack top.
