    I understood the concept clearly after watching the video, could you provide examples for other instructions such as add and addc, subb, mul, etc.

    Sir carry of substraction is called "borrow" that's why it's SUBB 👍👍

    why do we do -16 in DA?

  • @moordhansongade1502

    For ADD A,@R1, shouldn't it be A

    • @EngineeringFunda
      @EngineeringFunda  7 месяцев назад

      Yes, you are correct. I made an error in describing the instruction "ADD A,@R1". The correct interpretation is:
      𝐴←𝐴+[[𝑅1]]
      In this instruction, the contents of register R1 are considered as an address, and the content at that address is added to the accumulator A. Thank you for catching that mistake!

    In the example of 99H and 99H after adding 9+9=18 and then minus 16 so that is equal to 2 so why we gave carry ?pls rply .I didn't understand that step?

  • @venkataddala
    @venkataddala 18 часов назад

    hi sir good evening... i have a doubt here... in Decimal adjustment topic example no 3 ; 8+9=17 so in hexa decimal 16-17=1 so how can we use 16 for subtracting to make 1....................................... and Doubt no 2 : in example no 4.... 6+7=13 so you consider it as D.. why sir......? and D+6 =19 so from this why we using 16 to subtract from 19...?

      You need to learn hexadecimal addition and subtraction, in digital Electronics I have explained it.
