ANI

 

Syntax: ANI 8-bit

Where 8- bit is an immediate operand data.

Byte: 2byte

Addressing Mode: Immediate Addressing

Working: 

1.This is 2 byte instruction.

2. Microprocessor will allocate first byte for opcode and second byte for immediate data.

3. During execution of this instruction, microprocessor will perform Logical ANDing operation between content of Accumulator and Immediate data.

4. S, Z and  P  are modified. Cy is reset(Cy=0) and Ac is set (Ac=1).

Example: ANI 22H

where [A]= 11H

After execution of ANI 22H

[A] = 00H

 

 

A= 11 =  0001 0001

 =  22 =  0010 0010

 A=00    0000  0000

FLAG=  0101 0000 = 50H
