| * POP[.W] | Pop word from stack to destination | |
| * POP.B | Pop byte from stack to destination | |
| Syntax | POP dst | |
| POP.B dst | ||
| Operation | @SP → temp
SP + 2 → SP temp → dst |
|
| Emulation | MOV @SP+,dst or MOV.W @SP+,dst | |
| MOV.B @SP+,dst | ||
| Description | The stack location pointed to by the SP (TOS) is moved to the destination. The SP is incremented by 2 afterwards. | |
| Status Bits | Status bits are not affected. | |
| Example | The contents of R7 and the SR are restored from the stack. | |
POP R7 ; Restore R7
POP SR ; Restore status register
| Example | The contents of RAM byte LEO is restored from the stack. | |
POP.B LEO ; The low byte of the stack is moved to LEO.
| Example | The contents of R7 is restored from the stack. | |
POP.B R7 ; The low byte of the stack is moved to R7,
; the high byte of R7 is 00h
| Example | The contents of the memory pointed to by R7 and the SR are restored from the stack. | |
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
NOTE
System stack pointer
The system SP is always incremented by 2, independent of the byte suffix.
