Question

What are the categories in the vectored interrupt controller?

(a) Fast interrupt request

(b) Non vectored interrupt request

(c) Non-vectored IQR

(d) Fast interrupt request, Non vectored interrupt request and Non-vectored IQR

I got this question during an interview for a job.

The origin of the question is Microcontroller (ARM 7- Pipelining) topic in portion Prototyping Embedded Devices of IOT

Answer 1

Correct answer is (d) Fast interrupt request, Non vectored interrupt request and Non-vectored IQR

Best explanation: The vectored Interrupt controller accepts all the interrupts request inputs and categorizes them as Fast Interrupt Request, Vectored Interrupt Request, and Non Vectored IQR as defined by programmable settings. The programmable assignment scheme means that priorities of interrupts from the various peripherals can be dynamically assigned and adjusted.
