difference between hardware and software interrupts in 8085 microprocessor

Differentiate between hardware interrupts and software interrupts of 8085.

  • The software interrupt is initiated by the main program, but the hardware interrupt is initiated by an external device.
  • In 8085, the software interrupt cannot be disabled or masked but the hardware interrupt except TRAP can be disabled or masked.
