Assume that a 4-winding stepper motor is connected to the Port A of 8255 PPII at address 0280H. The stepper motor moves by an angle of 12° at every step. Write a program which checks ports B and C to decide the direction of the motor. If the MSB of Port B and LSB of Port C are both 1, the motor rotates in forward direction with 250 rpm. Otherwise, the motor rotates in the reverse direction with 500 rpm.
