8253/8254 Programmable Interval Timer Block diagram Complete

The Intel 8254 is a counter/timer device designed to solve the common timing control problems in microcom- puter system design. It provides three independent 16-bit counters, each capable of handling clock inputs up to 10 MHz. All modes are software programmable. The 8254 is a superset of the 8253.

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. To operate a counter, a 16-bit count is loaded in its register.
