在ASM 8086 ADC指令

问题描述:

当我使用 ADC 为〔实施例:

AL = 01 and BL = 02, and CF = 1

当我这样做:

ADC AL,BL 

威尔 AL 3 4 ? (与 CF 添加或不?)

Will AL be 3 or 4? (with the CF addition or without?)

有关 8086 ADC 指令几件事情

Syntax: adc dest, src
dest: memory or register
src:  memory, register, or immediate
Action: dest = dest + src + CF

显然动作说,进位标志( CF )将被列入除了这样的结果将是 4 不是 3

Clearly the action says the Carry Flag (CF) will be included in the addition so the result will be 4 not 3.
