Write assembly code using the CJNE command that performs the following operation and writes the result to P3. Here, N is the
number read from Pl. Assume that the maximum value for N is 22d or 16h.

Note: If it is assumed that information will come from any port, no value should be assigned to this port by software. To test the
accuracy of the written codes, the relevant port is selected in the Debugger as shown above and the active/passive status in the
boxes is changed for the desired value. Thus, it is accepted that value comes to the Port from the outside world. Do not forget that
ports are bridges between the physical world and the microcontroller.](https://content.bartleby.com/qna-images/question/609b9ff6-f247-4c64-a707-7dadc93cc506/815fcac2-6825-4c79-902b-f5ebe122af1c/fzyzqy_thumbnail.jpeg)
