Can 8259 he interfaced with 8085 via the trap pin?

Correct Answer: Yes so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set and so whenever my interrupt occurs depending upon priority it will be serviced also the ISR address for all interrupts will be same ie 0024H Interrupt via trap is nonmaskable, so it will be serviced immediately
