All other predefined events can be used in multiple when clauses. Predefined

Event Directory
The following sections list Neuron C events alphabetically, providing relevant
syntax information and a detailed description of each event.
flush_completes Event
The flush_completes event evaluates to TRUE, following a call to the flush( )
function, when all outgoing transactions have been completed and no more
incoming messages remain to be processed. For unacknowledged messages,
“completed” means that the message has been transmitted by the media access
control (MAC) layer. For acknowledged messages, “completed” means that the
completion code has been processed. In addition, all network variable updates
have completed.
