ARM Architecture - Power Modes
What is the main purpose of deep sleep mode in ARM architecture?
ATo reset the system to factory settings
BTo save power by shutting down most of the system
CTo increase the processing speed temporarily
DTo enable debugging features
Step-by-Step Solution
Solution:

  1. Step 1: Understand the function of deep sleep mode

    Deep sleep mode is designed to reduce power consumption by turning off most parts of the system when not in use.

  2. Step 2: Compare options with this function

    Only To save power by shutting down most of the system correctly describes saving power by shutting down most of the system.

  3. Final Answer:

    To save power by shutting down most of the system -> Option B

  4. Quick Check:

    Deep sleep mode = Power saving [OK]
Quick Trick: Deep sleep means power saving by shutting down [OK]
Common Mistakes:
  • Confusing deep sleep with speed boost
  • Thinking it resets the system
  • Assuming it enables debugging
