Notes on Using Real-Time OSes for R8C and M16C MCU Families
When using real-time OSes for the R8C and M16C families of MCUs, take note of the followingproblems:
●With task switching being delayed
●With dispatch disabled state
If an operation or event that necessitates task switching is performed by an interrupt generated while a service call is executed, task switching may not be done just at the end of the service call, but after a certain delay time. That is, task switching may be done after a call is made to any service call that changes a task's state, or after a kernel interrupt is completed.
Because confliction is generated in a ready queue, tasks in the ready state may not be executed. As a result, your system may not operate properly.
