The address of the INT 21h interrupt handler is located at what offset in the interrupt vector table?

When a signal is received, the CPU suspends its current activity to process the request. The technique used in this instance is: A' Signal of Interrupt Spooling B C' Interrupt Handling D Polling.

Chaining and hooking for a FIQ interrupt mechanism must begin at the Interrupt Vector Table offset. It.?

An ADC produces an interrupt request and the interrupt service routine runs and acquires a burst of data of 10 data values into a global array. What is a good way for the ISR to tell the main program there is new data in the array? Set a global flag variable. Do nothing. The main program has to check if the data array has changed. Pass the array as a return value from the ISR. Clear the interrupt flag in the ADC.

The hooking and chaining process for a FIQ interrupt mechanism must begin at the offset specified in the Interrupt Vector Table. It.?

Each item in the interrupt vector table represents a distinct collection of data.

If you want to hook and chain a FIQ interrupt method, the method's execution has to start at the supplied offset in the Interrupt Vector Table.
