Hello Aishwarya, I have been unable to find a means to lower the interrupt priority level of the currently active ISR. Therefore, I think my only option is to increase the priority of the interrupt source as a function of the nesting level. However, your warning about "interrupt handlers corrupting their own stack data" makes me think that I should probably explore other avenues first. Maybe your FreeRTOS port will provide further insights. Thank you again, Beat
