Ports A, B, and C can be individually programmed interfacint 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 its shaft in terms of steps, rather than continuous rotation as in case of AC or DC intertacing.

In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. It generates a clock pulse at OUT at regular interval programmed through preset count value.
