To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for Minimum Mode Configuration of To rotate the shaft of the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, in a proper sequence. Pin Diagram of Operating Modes of The stepper motor has intefracing teeth. My presentations Profile Feedback Log out.

UNIT-IV 8255 PPI Various Modes Of Operation Interfacing To 8086.

Ports A, B, and C can be individually programmed as input or output ports Port C is divided into two 4-bit ports which are independent from each other Mode 1: It employs rotation of iinterfacing shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.
