Question

Difference between vectored and non-vectored interrupt in 8085

Answer 1

The main difference between vectored and non-vectored interrupt is that in vectored interrupt the processor generates the new address automatically. For example, if 8085 microprocessor is interrupted through RST 5.5 pin the processor will multiply 5.5 by 8 and convert it to Hex address automatically. While in a non-vectored interrupt the user has to provide the address of subroutine using the CALL instruction.
