Consider the following x86 - assembly language instructions:
MOV AL, 153
NEG AL
The contents of the destination register AL (in 8 - bit binary notation), the status of Carry Flag (CF) and Sign Flag (SF) after the execution of above instructions, are1
AL = 0110 0110; CF = 0; SF = 0
2
AL = 0110 0111; CF = 0; SF = 1
3
AL = 0110 0110; CF = 1; SF = 1
4
AL = 0110 0111; CF = 1; SF = 0
