WebOct 7, 2024 · Interrupts¶. An interrupt service routine (ISR) is a function that executes asynchronously in response to a hardware or software interrupt. An ISR normally preempts the execution of the current thread, allowing the response to occur with very low overhead. Thread execution resumes only once all ISR work has been completed. WebAt time index 4 an interrupt (ISR) occurs and preempts the SysTick_Handler. RTX does not add any latency to the interrupt service execution. The ISR routine uses an RTOS-call that unblocks thread 4. Instead of switching to thread 4 immediately the PendSV flag is set to defer the context switching.
