1.Writethe program

2.Prepare the hex code of the program

3.Enter the hex code to trainer kit in suitable locations(eg:From 4100 H)

4.Give sufficient data for program in data memory(eg:From 4200 H)

5.Run the program

6.Check for output

The programming procedureis explained through an example. Consider the case of addition of two 8 bit numbers.

1.WRITE THE PROGRAM

2.PREPARE HEX CODE OF THE PROGRAM

Hex code is preparing in accordance with the Intel Hex file format.The hex code table is given below.Each instruction has a hex code. Consider the instruction ADD B.From the hex file format the corresponding hex code is 80.

Consider STA 4203 .The firstlocation should contain the hex code of STA. That is32.Next location should contain the LSB of 4203, that is 03.The next location should contain the MSB of the address,that is 42.

The hex code table is given below

The hex code of the above program is given below.

Write the meaning of each instruction in this column

3.ENTER THE HEX CODE TO THE TRAINER

The obtained hex code now can be enteredto the trainer. Assume the program is entering from location 4100. Now to enter the code,pressSUB key +4100+NEXTkey. Now the location will be 4100. Now start entering the program. After entering each code press the NEXT key to get the next location.

4.ENTER SUFFICIENT DATA

In the above program thetwo numberswhich are to be added are to be supplied. Supposethe data memory is from locations 4200.To writedatapressSUB key +4200+NEXTkey . Now the address will be 4200.Enter the first data in 4200.Now press NEXT key to get the next location .

5.EXCECUTE THE PROGRAM

Assume the program is from location 4100 and data memory is from 4200.Then the command to execute the program is SUB key+4100+EXEC key. Now therewill be an E symbol on the display . This indicates the running of program.

6. CHECKING DATA MEMORY FOR RESULTS

Afterfew seconds the running is stopping by an interrupt . Then the data memory can be read t get the result of running by theSUB key +4200+NEXTkey. In our exampleassume the input numbers are 05 and 04 .The output after running the program is given below.
