For example: mov al, byte ptr count ; treat count like a byte mov ax, word ptr newVal ; treat newVal like a word Webspecial purposes – the stack pointer (RSP) and the base pointer (RBP). In all cases, subsections of the registers may be used. For example, the least significant 2 bytes of RAX can be treated as a 16-bit register called AX. The least significant byte of AX can be used as a single 8-bit 1
