Problem: To show masking of lower and higher nibbles of 16bit number using 8086 Microprocessor.

Assumption:

• Number is stored at memory location 0600.
• Result will be stored at memory location 0602 and 0603.

Algorithm:

1. Load first number to the register AX.
2. Now move the content of register AL to memory location [0602].
3. Now move the content of register AH to memory location [0603].
4. Terminate the program.

Program:

	MOV     AX, [0600]
	MOV     [0601], AL
	MOV     [0602], AH
	HLT

Observation:

    INPUT:
    0600: 1112

    OUTPUT:
    0602:0012
    0603:0011

Hence, we successfully masked the higher and lower nibble of a 16 bit number using 8086 Microprocessor.
