Choose the software interrupt from the following list:

Question

In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.

Answer 1

Software interrupts are program-initiated, triggered by instruction execution rather than external hardware signals. RST 5 exemplifies a software interrupt, explicitly invoked by a program for specific task handling. In contrast, INTR is a general-purpose hardware interrupt, RST 6.5 is a vectored hardware interrupt, and TRAP is a non-maskable hardware interrupt.

List I	List II
A. Supervisor mode	I. Entered when the processor encounters a software interrupt instruction
B. Abort Mode	II. Entered in response to memory fault
C. Fast Interrupt Mode	III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source
D. Interrupt Mode	IV. Entered whenever the processor receives an interrupt signal from any other source
