Block diagram of Intel 8253 The timer has three counters, numbered 0 to 2. [7] Each channel can be programmed to operate in one of six modes. Once programmed, the channels operate independently. [1] Each counter has two input pins - "CLK" ( clock input) and "GATE" - and one pin, "OUT", for data output.
