堆栈指针 (TOS) 指向的堆栈位置被移动到目标。之后,堆栈指针递增 2。
状态位不受影响。
R7 的内容和状态寄存器被从堆栈中恢复。
POP R7 ; Restore R7
POP SR ; Restore status register
RAM 字节 LEO 的内容被从堆栈中恢复。
POP.B LEO ; The low byte of the stack is moved to LEO.
R7 的内容被从堆栈中恢复。
POP.B R7 ; The low byte of the stack is moved to R7,
; the high byte of R7 is 00h
从堆栈中恢复 R7 指向的存储器内容和状态寄存器。
POP.B 0(R7) ; The low byte of the stack is moved to the
; the byte which is pointed to by R7
; Example: R7 = 203h
; Mem(R7) = low byte of system stack
; Example: R7 = 20Ah
; Mem(R7) = low byte of system stack
POP SR ; Last word on stack moved to the SR
系统堆栈指针
系统堆栈指针 (SP) 始终递增 2,与字节后缀无关。
