* POP[.W] | 从堆栈中弹出字到目的 | |
* POP.B | 将字节从堆栈弹出至目的 | |
句法 | POP dst | |
POP.B dst | ||
操作 | @SP → temp SP + 2 → SP temp → dst | |
仿真 | MOV @SP+,dst 或 MOV.W @SP+,dst | |
MOV.B @SP+,dst | ||
说明 | SP 指向的堆栈位置被移动到目的。之后,SP 被增加 2。 | |
状态位 | 状态位不受影响。 | |
示例 | R7 和 SR 的内容被从堆栈中恢复。 |
POP R7 ; Restore R7
POP SR ; Restore status register
示例 | 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.
示例 | 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
示例 | R7 和 SR 指向的存储器的内容被从堆栈中恢复。 |
POP.B 0(R7) ; The low byte of the stack is moved to the
; the byte which is pointed to by R7
: 示例: R7 = 203h
; Mem(R7) = low byte of system stack
: 示例: 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 SP 被一直加 2,而与字节后缀无关。
