Assembly language is a low-level programming language that is closely related to the machine code instructions of a specific computer architecture. It uses mnemonic codes to represent specific instructions that can be executed by the computer's processor.

To handle a button press in assembly language, you typically need to interact with the hardware of the system. The exact steps will depend on the specific hardware and architecture you are working with, but here is a general outline of how you might handle a button press using assembly language:

1. Set up the necessary hardware registers to enable input from the button. This may involve configuring specific pins or ports to act as input pins.

2. Continuously monitor the state of the button using a loop. This can be done by reading the value of the input pin associated with the button.

3. When the button is pressed, the corresponding input pin will change its state. You can check for this change by comparing the current state of the input pin with its previous state. If the state has changed, it means the button has been pressed.

4. Once the button press is detected, you can perform the desired actions. This might involve updating the display, changing the program flow, or any other task you want to accomplish in response to the button press.

5. After handling the button press, you can either continue monitoring the button state or exit the loop, depending on your program requirements.

It's important to note that the specific implementation details will vary depending on the hardware and architecture you are working with. You will need to consult the documentation or specific resources for your target system to get the exact instructions and registers needed for handling button presses in assembly language.
