CHAPTER 4 TASK MANAGEMENT
4.14.6 Activating task exception processing routines
A task exception processing routine is activated by the kernel when all of the following four conditions are met.
鈥?/div>
Task exceptions are in the enabled state
鈥?/div>
The pending exception source is not 0
鈥?/div>
The task is in the running state
鈥?/div>
The non task context of an interrupt service routine or a cyclic handler is not under execution
In other words, the conditions for tasks when task exceptions are enabled are:
(1) The task has been put in the running state by the issuance of a dispatch and the pending exception source is
not 0 at that time
(2) The pending interrupt source is not 0 when interrupt processing has finished and processing returns to the task
(3) ras_tex has been issued by a task to itself
(4) The pending interrupt source is not 0 when the task exception processing routine has finished
In the above cases, the task exception processing routine is activated immediately before control is shifted to the
task (main processing routine). The processing flow when a task exception processing routine is activated is shown
below.
