How can the processor ignore other interrupts when it is servicing one...
Turning off the interrupt request line:
- One way for the processor to ignore other interrupts when servicing one is by turning off the interrupt request line. This prevents any further interrupts from being signaled to the processor until it has finished servicing the current interrupt.
Disabling the devices from sending the interrupts:
- Another method is to disable the devices from sending interrupts while the processor is servicing one. This can be done by configuring the devices to hold off sending interrupts until they receive a signal from the processor indicating that it is ready to handle them.
Using edge-triggered request lines:
- Edge-triggered request lines can also help the processor ignore other interrupts while servicing one. With edge-triggered interrupts, the processor only responds to the interrupt signal when it transitions from low to high or high to low, ignoring any other changes in the signal while it is already servicing an interrupt.
Combination of methods:
- By employing a combination of these methods, the processor can effectively handle interrupts one at a time without being interrupted by other devices. This helps ensure that the processor can complete the necessary tasks associated with the current interrupt before moving on to the next one.
