Which pin of 8253 is used for the generation of an external interrupt

1.	Which pin of 8253 is used for the generation of an external interrupt signal?(a) OUT pin(b) IN pin(c) Interrupt pin(d) Ready pinI have been asked this question in exam.Origin of the question is Timer-II in portion Basic Peripherals of Embedded Systems
Answer» Right answer is (a) OUT pin Easy explanation: The Intel 8253 TIMER has no interrupt PINS. THEREFORE, the timer OUT pin is USED to GENERATE an external interrupt signal.
