• Timer interrupts synchronization in Cortex M4
    Hi, I am working on Cortex M4 based Microcontroller. I have one timer(TIM0) running and when it gets restarted, GPIO pin is set. I have one more timer (TIM1) running separately and it sets another...
  • Changing interrupt priority to prevent nesting
    Hi, I'm working on M0+, but the question applies to M3 or M4 too. I have the following situation: 2 interrupt sources inject events on a state machine that must handle each event separately (not nested...
  • What is the priority between synchronous data abort and FIQ in Cortex-R5F?
    Hi, With Cortex-R5F, we have a case where a read to the L2 memory generates both a synchronous data abort and an FIQ with near-zero delay. We are reading from RAM while the RAM is in test mode and...
  • Get current active interrupt priority
    Hi everybody, We are working on a simple priority RTC (run to completion) framework for the Cortex M3/M4. Thanks to the NVIC/BASEPRI, we got most of this functionality for free but we want to extend it...
