Thus, the ability to program an 8051 is an important skill for anyone who plans to develop products that will take advantage of microcontrollers. Uploaded on Aug 09, 2014. Web8051 Interrupt System. There are five different ways to interrupt an 8051. Two of these are from external electrical signals. The other three are caused by internal 8051 I/O hardware operations. The two external inputs come from the INT0 and INT1 inputs. A logic 0 on INT0 sets bit IE0 (interrupt external 0) in the timer control register.
