Block Diagram For 8253

What is 8253 ?

The Intel 8253 is a programmable interval timer or PIT chip. It performs counting and timing functions using three 16-bit counters for the microcomputers. Each counter has two specific input pins and one output pin. These can be programmed to perform the counting process in a binary mode. The modes of the 8253 determine how these counters work and also regulate the one output pin as well....
