WebNested interrupts and ISR stack¶ On R5F, When an interrupt is triggered, the CPU switches to IRQ mode and uses the IRQ stack. IRQ interrupts are disabled by HW at this point. In the ISR handler, some CPU state is saved to IRQ stack and mode is switched to SVC mode and therefore SVC stack; IRQs are then enabled, i.e nested interrupts are … WebJan 11, 2024 · freertos学习,FreeRTOS5中内存管理学习,freeRTOS 参数之configUSE_PREEMPTION,FreeRTOS. ...
