Hi,
I have one query related to RTOS. We are using Nucleus RTOS. But my query is Generic. Suppose if a task is executing and if it's preemption is disabled, then is the task becoming atomic in nature? What i am asking here is, once the preemption of a task is disabled, can ISR routine interrupts interrupt the task? disabling the preemption of a task means, all other tasks cannot interrupt the particular task that is executing. so, can ISR in this situation can cause the interruption? and by disabling the preemption, is it a meaning of disabling the ISR aslo??
