Question

Write or type AVR Assembly code for this scenario. Please turn this sheet in with your solution. Add the integer values from d4 to d9 using a loop. Inside of a loop perform these operations 60 times with a 1 second delay of each input Input two 4-bit value from the lowest and highest bits of Port C respectively Subtract the lower input from the higher input and output the value (in hexadecimal) on a 7-segment display connected to Port D. If the value is negative output the character X If the difference in positive, the result should also be stored in memory starting at location 0x1000

Explanation / Answer

As per the givedata wrote the programas shown below
