8085 Program to alternately display 00 and FF in the data field

Now let us see a program of Intel 8085 Microprocessor. In this program we will generate 00H and FFH alternatively.

Problem Statement:

Write 8085 Assembly language program to generate 00H and FFH alternatively.

Discussion:

The 00H and FFH are changed alternatively in each second. So we need one second delay. We have created delay subroutine to generate 1s delay.

Note: Here for simplicity we are storing the numbers into memory. To show the numbers, we can use 7 – segment display and other display function for showing it into the display.

Input:

Here we are not providing any input.

Program:

Output:

The numbers are storing into memory location 8000H.
