Programmable interval timer.
Here we will see the control words and the operation modes of the 8254 programmable interval timer chip. Before discussing its operating modes and control word properties, we should know about some important facts of this chip. When the chip is powering up, the state is undefined. The mode, count value, and outputs are undefined in that time.

The Intel 8253 and 8254 are Programmable Interval Timers (PTIs) designed for microprocessors to perform timing and counting functions using three 16-bit registers. Each counter has 2 input pins, i.e. Clock & Gate, and 1 pin for “OUT” output.The control word register format of the 8254 programmable interval timer is as shown in the figure below: The control word register bits, SC 1 and SC 0, select the control word register for the counter and are used to initialize the counters. A 0 and A 1 select counters, but they are used to read/load counters by microprocessor.Specifications.
