ARM Architecture - Power Modes
What happens to the CPU clock when ARM architecture enters deep sleep mode?
What happens to the CPU clock when ARM architecture enters deep sleep mode?
easy📝 Conceptual Q1 of 15
Step-by-Step Solution
Solution:
Step 1: Understand deep sleep mode purpose
Deep sleep mode is designed to reduce power consumption by stopping the CPU clock.Step 2: Identify CPU clock behavior in deep sleep
In deep sleep, the CPU clock is stopped, halting processor activity to save power.Final Answer:
The CPU clock is stopped to save power -> Option BQuick Check:
CPU clock stopped = A [OK]
Quick Trick: Deep sleep stops CPU clock to save power [OK]
Common Mistakes:
- Thinking CPU clock speeds up in deep sleep
- Assuming CPU clock remains active
- Confusing deep sleep with standby mode
