1.5 Software Stack Frame Pointer

A frame is a user-defined section of memory in the stack, used by a function to allocate memory for local variables. W14 has been assigned for use as a Stack Frame Pointer with the link (LNK) and unlink (ULNK) instructions. However, if a Stack Frame Pointer and the LNK and ULNK instructions are not used, W14 can be used by any instruction in the same manner as all other W registers. See Software Stack Frame Pointer for detailed information about the Frame Pointer.
