8085 Program to simulate decimal down counter

Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to simulate the decimal down counter.

Problem Statement:

Write 8085 Assembly language program to simulate decimal down counter.

Discussion:

In this section we are simulating the decimal down counter. Here the counter will count 100 decimal numbers from 99 to 0. All values will be updated in each 0.5 seconds. For decimal count we are using the DAA instruction.

Note: Here for simplicity we are storing the numbers into memory. To simulate it like a counter we can use 7-segment display to show the numbers

Input:

Here we are not providing any input.

Flow Diagram:

Program:

Output:

The numbers are storing into memory location 8000H.
