For what purpose is the SP value utilized in the 0x0 in cortex-M4 during its inception?

edit

The SP (Stack Pointer) value in the 0x0 in Cortex-M4 is utilized to store the initial value of the stack pointer. The stack pointer is a register that is used to point to the top of the stack in the memory. During the Cortex-M4's inception, the stack pointer needs to be initialized to a valid memory location for the processor to function properly. The SP value at 0x0 is used as the initial value of the stack pointer, which is then incremented or decremented as required, as the processor executes code and pushes or pops data to or from the stack.
