The SERVICE~ pin is active low and the service pin message is sent at most once per SERVICE~ pin transition. The
service pin message goes into the next available priority or non-priority output network buffer. Devices in the
applicationless state that do not have an external pullup will transmit the SERVICE~ pin message after every reset.
