WebD5H ⊕ 0FH = DA H (AL) = 11011010B = DAH . MP 90 Note that this operation complements the logic state of those bits in AL that are 1s in the immediate operand. The last instruction, NOT AL, inverts each bit of AL. Therefore, the final contents of AL become (AL) = 11011010B = 00100101B = 25H WebOct 17, 2009 · Example: MOV AL, 0Fh ; AL = 0Fh (15) DAA ; AL = 15h RET C Z S O P A r r r r r r DAS No operands Decimal adjust After Subtraction. Corrects the result of subtraction of two packed BCD values.

Web(AL) = 11010101B = D5H This operation is equivalent to setting the two most significant bits of AL. The fourth instruction is an exc1usive-OR operation of the contents of AL with … WebThe AL register is the implied source and destination operand. The DAA instruction is only useful when it follows an ADD instruction that adds (binary addition) two 2-digit, packed BCD values and stores a byte result in the AL register. The DAA instruction then adjusts the contents of the AL register to contain the correct 2-digit, packed BCD ...
