ARM Architecture - Exception and Interrupt Model
Which of the following correctly describes the second entry in the ARM vector table?
AReset handler address
BInitial stack pointer address
CUndefined instruction handler
DNon-maskable interrupt handler
Step-by-Step Solution
Solution:

  1. Step 1: Recall vector table order

    The first entry is the initial stack pointer, so the second entry is the reset handler.

  2. Step 2: Confirm second entry role

    The reset handler is the address where the processor starts executing after reset.

  3. Final Answer:

    Reset handler address -> Option A

  4. Quick Check:

    Second entry = Reset handler address [OK]
Quick Trick: Second entry always points to reset handler [OK]
Common Mistakes:
  • Mixing up with interrupt handlers
  • Choosing stack pointer again
  • Confusing with exception handlers
