3. A stepper motor is connected with the 8086-microprocessor system using the 8255-programmable peripheral interfacing IC. The four phases of the motor are connected to Port-A as shown in figure 1. Two control switches are connected to Port-C. The control on motor should be done as follows: PC: PC Motor Operation 0 0 1 1 0 1 0 1 Off 1-phase Full-step mode 2-phase Full-step mode Half-step mode (a) Find the addresses of the ports and control register, (b) Find the control word, (c) Wite an assembly language program to perform the job as mentioned.
