tasks Simulate a PIC16F877A microcontroller-based system using the Proteus Professional Suite that must receive the data from the input devices, process the data as per the required operation, and display the result on output device. The interfacing connection is provided in figure 1. Figure 1: Interfacing connection To fulfill the requirement of simulating a microcontroller-based system using Proteus Professional Suite, an assembly language program should be written using appropriate compilation tool. The task comprises of the following steps. The three 4-bit numbers X,Y and Z are to be received from the respective input port
