FreeRTOS - Interrupt Management

What is the main purpose of nested interrupt handling in FreeRTOS?

AAllow higher priority interrupts to interrupt lower priority ones

BDisable all interrupts during task switching

CPrevent any interrupt from occurring during critical sections

DRun all interrupts sequentially without interruption

Step-by-Step Solution

Solution:

Step 1: Understand interrupt priorities
Nested interrupts allow interrupts with higher priority to interrupt those with lower priority.
Step 2: Relate to FreeRTOS behavior
FreeRTOS supports nested interrupts to ensure urgent tasks get immediate attention.
Final Answer:
Allow higher priority interrupts to interrupt lower priority ones -> Option A
Quick Check:
Nested interrupts = higher priority interrupts interrupting lower priority [OK]

Quick Trick: Nested interrupts let urgent interrupts pause less urgent ones [OK]
