3.2.3.1.9.7 Services from UART
The first character of each service sent to the host is the control field. The control field contains the
information about the TP-UART-Service. There are 3 types of services sent to the host, the EIB-Layer-
2-Services, immediate acknowledge services and the special TP-UART-Services. The EIB-Layer-2-
Services contains information about its class and a flag containing the information whether the LPDU is
a repeated one. The immediate acknowledge services are only sent in busmonitormode and includes
informations about successful sending. The TP-UART-Services are to inform the host about the
communicationstate or to reset the communication.
