Please just do questions 10,11, and 12 What is the name given to a routine that is executed in response to an interrupt What are the advantages of using interrupts to handle data inputs and outputsWhat are the requirements for interrupt processing How do you enable other interrupts when the HCS12 is executing an interrupt service routine E6.5 Why would there be a need to promote one of the maskable interrupts to the highest priority among all maskable interrupts Write the assembler directives to initialize the IRQ interrupt vector located at $3000 for the EVB mode of the D-Bug12 monitor.What is the last instruction in most interrupt service routines What does this instruction do Suppose that the HCS12 is executing the following instruction segment and the IRQ Interrupt occurs when the TSY instruction is being executed. What will be the contents of the top 10 bytes in the stack ORG $2000 LDS #$2000 CLRA LDX #$0 BSET 10.X $48 LDAB #$40 INCA TAP PSHB TSY ADDA #10 Write a subroutine to convert all the lowercase letterExplanation / Answer
(11) Wait State:
A wait state is a delay experienced by a computer processor when accessing external memory or another device that is slow to respond.
When the processor needs to access external memory, it starts placing the address of the requested information on the address bus. It then must wait for the answer, that may come back tens if not hundreds of cycles later. Each of the cycles spent waiting is called a wait state.
(12) Stop state:
A computer processor is described as idle when it is not being used by any program.
Every program or task that runs on a computer system occupies a certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle.
Most operating systems will display an idle task, which is a special task loaded by the OS scheduler only when there is nothing for the computer to do. The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority.
