Digital Clock Using MicrcontrollerProcedure:In order to achieve the objective, the steps followed are stated below:The first step was to develop an assembly language program of a digital clock for the 8085 microprocessor. It was done by developing a counter which consisted of three phases in the form of hh:mm:ss. This result was then displayed on an interfaced LCD.
In second step the OPCODE Table for the corresponding assembly language program was developed and the microprocessor board was prepared.The LCD was interfaced with the 8255 on the microprocessor board by using the provided cable.Then the after turning on the microprocessor board, the corresponding OPCODE for the assembly language program was keyed in to the microprocessor.The program was executed and the results were observed on LCD display.No problems were found and the results were satisfactory.In order to achieve the objective, the steps followed are stated below:The first step was to develop an assembly language program of a digital clock for the 8085 microprocessor.

On the first page, the CMD and the MDP information was supplied to enable the execution of the microprocessor at a certain time in order to create the associated time format and register.
[…]
The above steps were followed for a number of registers and the assembler on these registers.
[…]
The first step was to write the actual registers using the microprocessor in a given step using the microprocessor board.
The assembly of assembly language program was then performed and the results found in the LCD display was satisfactory. All the steps were implemented on a working system.
With support from the Microprocessor Company (the Company) the microprocessor can now be programmed as easily as a computer with a serial number.
[…]
I also used microchips for the instructions to start, stop, control operation of the microprocessor.
[…]
The microprocessor also supports serial-input. It can be used even when a digital clock is provided or on the external power source, as long as it is connected to the internal power source of the microprocessor board (the internal power source) using the same cable.
[…]
The microprocessor can be programmed independently over different digital clocks to provide better control over the output signal. When an external power source is present, power is not lost by any of the six pins of the microprocessor.
The following instructions indicate that a microprocessor can provide a high-frequency signal to the memory controller between 4 (P) to 7 (E) pins, and 8 (Q) to 10 (I) pins.
[…]
In the first step of the assembly, the analog clock for the microprocessor is identified and executed.
In the second step, the internal clock for the microprocessor is assigned to the microprocessor. It is used to indicate how far the process is to execute and to control an internal process such as the processor.
In the third step, the internal clock for the microprocessor is determined so that any interrupt is triggered when its processor is idle without any interrupt to the microprocessor.
[…]
In the last step of the assembly, the internal clock for the microprocessor is specified so that in the event of an interrupt, an interrupt can be triggered to begin executing.
In the process of building up the microprocessor, in the first step of the microprocessor, we introduced a new assembly language program which is known as HMP (Instruction Pattern Language HMP). This has been modified a number of times since the 8085. It is intended to allow an assembler to dynamically determine the correct instruction for the microprocessor. The instruction is then automatically coded and then used over and over to assemble the microprocessor at the address of the address of the instruction.
[…]
The instruction is given as a pointer to the microprocessor assembly. It can be used to construct the correct address of the microprocessor instruction by calling it directly in the program.
The instruction could also be used to identify other interrupts. It might specify whether the interrupting code has been called as a different assembly language.
