* INV[.W] | 反转目的 | |
* INV.B | 反转目的 | |
句法 | INV dst 或 INV.W dst | |
INV.B dst | ||
操作 | .not.dst→dst | |
仿真 | XOR #0FFFFh,dst | |
XOR.B #0FFh,dst | ||
说明 | 目的操作数被反转。原先的内容丢失。 | |
状态位 | N: | 如果结果为负,则置 1,如果为正,则复位 |
Z: | 如果 dst 包含 0FFFFh,则置 1;否则复位 | |
如果 dst 包含 0FFh,则置 1;否则复位 | ||
C: | 如果结果不为零,则置 1;否则复位 (=.NOT.零) | |
V: | 如果初始目的操作数为负,则置 1;否则复位 | |
模式位 | OSCOFF,CPUOFF 和 GIE 不受影响。 | |
示例 | R5 的内容被求反(2s 补数)。 |
MOV #00AEh,R5 ; R5 = 000AEh
INV R5 ; Invert R5, R5 = 0FF51h
INC R5 ; R5 is now negated, R5 = 0FF52h
示例 | 存储器字节的内容被求反。 |
MOV.B #0AEh,LEO ; MEM(LEO) = 0AEh
INV.B LEO ; Invert LEO, MEM(LEO) = 051h
INC.B LEO ; MEM(LEO) is negated, MEM(LEO) = 052h
