Question

Program the below math operation using the 8051 microcontroller, and atore the result in R.3: (20×(5+7))/8 mod6

Answer 1

To program the math operation (20×(5+7))/8 mod6 using the 8051 microcontroller and store the result in R.3, you can follow these steps.

Step-by-step explanation:

To program the given math operation using the 8051 microcontroller and store the result in R.3, follow these steps:

1. Load the values 20, 5, and 7 into appropriate registers.
2. Add the values of 5 and 7 to get the sum.
3. Multiply the obtained sum by 20.
4. Divide the result by 8.
5. Find the remainder (mod6) of the division.
6. Store the final result in R.3.

For example:

MOV A, 5 ; Load value 5 into accumulator
ADD A, 7 ; Add 7 to accumulator
MOV R3, A ; Store result in R.3
