-Both for µC/OS-III and FreeRTOS, it is normally considered best practice to keep ISRs as short as possible. If there is a long-term response/pending in the IRS, As same as we called The tick task (OS_TickTask(), os_tick.c) and The ISR handler task (OS_IntQTask(), os_int.c) in the µC/OS-III, FreeRTOS also provides the ISR Handler mechanism called Deferred Interrupt Handling. Typically, it's to deliver the processing necessitated by the interrupt to be performed at a high priority unblocked task( High priority deferred interrupter handler task ), rather than within the ISR.+Generally, both for µC/OS-III and FreeRTOS, it is considered best practice to keep ISRs as short as possible.
