4.2.1
set_flg (Set Eventflag)
iset_flg (Set Eventflag for Interrupt)
[Function]
Sets an event flag.
[Remarks]
The event flag indicated by flgid is set to 1. If a task exists that has been made to wait for the event flag by
“wai_flg, cwai_flg”, the task is released from the WAIT state and placed in the READY state.
Two or more tasks can wait for the same event flag. In this case, the tasks can be released from the WAIT
state when “set_flg” is issued once.

set_flg = 10
