CHAPTER 20 REAL-TIME OS EMBEDDED MB91302A-010 USER'S GUIDE
❍ Task definition tab
Register user tasks. Start registration in order from ID number 1. Even though the number of
user tasks for the actual system is less than 64, be sure to register 64 tasks. At this time, set the
startup priority levels, stack, and initial state of unused user tasks using D'32 (minimum priority
level), H'60 (minimum stack value acceptable), and DORMANT (idle state), respectively, not to
start these empty user tasks.

Even for an unused user task, write a vacant source code in C source code and compile it along
with other user tasks to be used for the system. The following is an example of empty source
code concerning unused task.
This development example assumes the following with regard to user tasks.
$ Number of tasks
$Stack size
$ Initial situation
$ Startup prioritized
This development example requires the following settings with the task definition tab of
Configurator.
task ID1 to ID30
task ID31 to ID40 Stack (S)
task ID41 to ID50 Stack (S)
task ID51 to ID64 Stack (S)
