• 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...
  • Priority of Systick timer M0+
    Hello everyone, I'm using a MKL05Z32 of Freescale that has a Cortex-M0+. I would like to know the priorit of the Systick timer available to use. Thanks. Frederico
  • Current priority level of processor
    Hi, I have been reading about the exception mechanism of Cortex-M (M4 to be precise). The exception request is accepted by the processor if the current priority level of the processor is less than the...
  • Cortex-M4 interrupt priority dynamically change while in ISR
    Hello, I am using STM32F407ZGT6 Cortex-M4 microcontroller. I am interested in changing the priority of a certain interrupt while servicing the same interrupt. Is that possible? More elaborately, lets...
  • A question about interrupt priority degrade
    Hi guys, I found in armv8-arch ref manual that when PRIS bit in the AIRCR is set, the priority of non-secure handler is mapped to the bottom of the priority range. So I did an experiment. I configured...
