easy📝 Conceptual Q1 of 15
ARM Architecture - Exception and Interrupt Model
What does NVIC stand for in ARM Cortex-M microcontrollers?
ANon-Volatile Interrupt Circuit
BNetwork Vector Interrupt Controller
CNested Vectored Interrupt Controller
DNested Vector Input Controller
Step-by-Step Solution
Solution:

  1. Step 1: Understand the acronym NVIC

    NVIC is a standard term used in ARM Cortex-M microcontrollers to manage interrupts.

  2. Step 2: Match the full form

    NVIC stands for Nested Vectored Interrupt Controller, which handles nested interrupts efficiently.

  3. Final Answer:

    Nested Vectored Interrupt Controller -> Option C

  4. Quick Check:

    NVIC full form = Nested Vectored Interrupt Controller [OK]
Quick Trick: NVIC always means Nested Vectored Interrupt Controller [OK]
Common Mistakes:
  • Confusing NVIC with network terms
  • Mixing up 'vector' and 'input' in the name
