There are 40 pins in the original 8086 microprocessor. write the name of the pin that best matches the given description. if this pin is active, the databus is being read into the cpus internal data bus. works with the wait instruction: is set when the wait instruction is executed. if the pin is low then the cpu will idle. when high, the cpu is 'ready' this is the interrupt request pin. pin gets set high when an external interrupt is present non-maskable interrupt, this pin will ignore the interrupt flag.
