QUESTION $1$

Assume that before the instruction is executed, the flags are $CF=0,ZF=0$ and $SF=0$ and the

Registers have the values $AL=035,BL=00FCL=025$ and $DL=078.$

What are the values of the flags after the instruction ADD AL$,0$x$90$ executes?

$CF=$

$ZF=$

$SF=$

QUESTION $2$

The following instruction is executed. Assume that before execution, register R$15$ contains $0$x$62,$ and the flags are $ZF=0,SF=0,$ and $CF=1.$ Ox indicates hexadecimal; do not include a $0$ with your answer.

Instruction: CMP R$15,0$xD$5$

After execution, register R$15$ contains $($in Hex$)$ and the flags will be ZF$=$

$SF=,$ and $CF=$

QUESTION $3$

The following instruction is executed. Assume that before execution, register R$12$ contains $0$x$05,$ and the flags are $ZF=1,SF=0,$ and $CF=0.$ Ox indicates hexadecimal; do not include a $0x$ with your answer.

Instruction: CMP R$12,0$xEC

After execution, register R$12$ contains

$($in Hex$)$ and the flags will be $ZF=.$

$SF=$ and $CF=$
