Link Start/Stop
This function stops the cyclic transmission during debugging and other operations. (Data reception from a slave station and
data sending from the own station are stopped.)
Also, the stopped cyclic transmission is restarted. This function does not stop or restart transient transmission.
Cyclic transmission can be started and stopped using link special relay (SB) and link special register (SW).
