Logical instructions in 8086 microprocessor

Logical instructions are the instructions which perform basic logical operations such as AND, OR, etc. In 8086 microprocessor, the destination operand need not be the accumulator.

Following is the table showing the list of logical instructions:

OPCODE	OPERAND	DESTINATION	EXAMPLE
AND	D, S	D = D AND S	AND AX, 0010
OR	D, S	D = D OR S	OR AX, BX
NOT	D	D = NOT of D	NOT AL
XOR	D, S	D = D XOR S	XOR AL, BL
TEST	D, S	performs bit-wise AND operation and affects the flag registor	TEST [0250], 06
SHR	D, C	shifts each bit in D to the right C times and 0 is stored at MSB position	SHR AL, 04
SHL	D, C	shifts each bit in D to the left C times and 0 is stored at LSB position	SHL AX, BL
ROR	D, C	rotates all bits in D to the right C times	ROR BL, CL
ROL	R, C	rotates all bits in D to the left C times	ROL BX, 06
RCR	D, C	rotates all bits in D to the right along with carry flag C times	RCR BL, CL
RCL	R, C	rotates all bits in D to the left along with carry flag C times	RCL BX, 06

Here D stands for destination, S stands for source and C stands for count.
They can either be register, data or memory address.
