• Cortex-M: Does the event register only get set when an IRQ changes from not pending to pending?
    I recently had a race-condition in an application on a Cortex-M4 microcontroller, because I used a wrong order of __SEV() and __WFE() instructions to put my chip to sleep. While debugging this issue,...

  • Pending interrupt status
    Hello, If there is a pending interrupt status already set, but it is not being handeled yet, is it possible that somehow that interrupt will no longer have pending status (pending status will disappear...

    Im using irq0 to generate an interrupt. when i debug the code, the values for SMR and SVR register are correct (as i can see in the AIC window). But the ISR is never serviced. and the pending flag for...
