5-5 TASK MANAGEMENT INTERNALS
5-5-1 TASK STATES
From a μC/OS-III user point of view, a task can be in any one of five states as shown in
Figure 5-6. Internally, μC/OS-III does not need to keep track of the dormant state and the
other states are tracked slightly differently. This will be discussed after a discussion on task
states from the user’s point of view. Figure 5-6 also shows which μC/OS-III functions are
used to move from one state to another. The diagram is actually simplified as state
transitions are a bit more complicated than this.
