Figure 14. Neuron Firmware Scheduling of Nonpriority and Priority When Clauses
Note that application interrupts, supported by Series 5000 chips, execute
asynchronously, and are not governed by the scheduler. See
on page
153 for more information.
Incoming messages and network variable updates use application input buffers,
which are processed by when(msg_arrives) and when(nv_update_occurs) tasks,
respectively.
