The Programmable Interval Timer (PIT) chip (also called an 8253/8254 chip) basically consists of an oscillator, a prescaler and 3 independent frequency dividers.Each frequency divider has an output, which is used to allow the timer to control external circuitry (for example, IRQ 0).

This mode is similar to mode 4 except that the counting is initiated by a signal at the gate input, which means it is hardware triggered instead of software triggered. After it is initialized, the output goes high. When the terminal count is reached, the output goes low for one clock cycle.
