9.4 Emergency Request Protocol

Emergency messages are triggered if an internal fault occurs. The transmission is
executed via the mailbox interface.
The Emergency Service is used by the server to transmit diagnostic messages to the
client. Each diagnostic event transmitted by the server to the client is also reconfirmed
by transmission of the reset error code when the diagnostic event is no longer present.
