ARM Architecture - Power Modes

Which component typically remains active during ARM's deep sleep mode to allow wake-up?

ACPU core

BAll peripherals

CGraphics processor

DSystem timer or interrupt controller

Step-by-Step Solution

Solution:

Step 1: Identify components active in deep sleep
During deep sleep, most components stop, but system timer or interrupt controller stays active to detect wake events.
Step 2: Confirm which component allows wake-up
The system timer or interrupt controller monitors signals to wake the CPU from deep sleep.
Final Answer:
System timer or interrupt controller -> Option D
Quick Check:
Wake-up component = C [OK]

Quick Trick: Interrupt controller stays active to wake CPU [OK]
