9.5.2. Non-Vectored Interrupts

Try these first

1. 1.

   What is a non-vectored interrupt?

   Hint

   Think about how it differs from vectored interrupts.

2. 2.

   Why might non-vectored interrupts introduce latency?

   Hint

   Consider the shared ISR scenario.

3. 3.

   What does a non-vectored interrupt require the CPU to do?

   • Point directly to ISR
   • Identify the source post-trigger
   • Ignore the source

   Hint

   Consider how an ISR is used.

4. 4.

   Non-vectored interrupts are typically less efficient than vectored interrupts. True or False?

   • True
   • False

   Hint

   Think about the implications of shared ISRs.

5. 5.

   You are designing a simple thermostat with multiple sensors (temperature, humidity). Explain how you would implement non-vectored interrupts to handle readings from these sensors.

   Hint

   Think about how to monitor each sensor's status.

6. 6.

   Discuss the potential impact on system performance when using non-vectored interrupts in a high-frequency data logging application.

   Hint

   Evaluate the trade-offs between speed and system simplicity.
