FreeRTOS - Interrupt Management

Which of the following is the correct way to declare an ISR that uses FreeRTOS API functions?

Avoid ISR_Handler(void) __attribute__((naked));

Bvoid ISR_Handler(void) __attribute__((used));

Cvoid ISR_Handler(void) __attribute__((interrupt));

Dvoid ISR_Handler(void) __attribute__((interrupt, used));

Step-by-Step Solution

Solution:

Step 1: Identify correct ISR attribute for FreeRTOS
FreeRTOS requires ISRs to be declared with the 'interrupt' attribute to handle context saving properly.
Step 2: Check other attributes
'used' and 'naked' are not standard for FreeRTOS ISR declarations and may cause issues.
Final Answer:
void ISR_Handler(void) __attribute__((interrupt)); -> Option C
Quick Check:
ISR declaration with interrupt attribute = Correct [OK]

Quick Trick: Use __attribute__((interrupt)) for FreeRTOS ISRs [OK]
