3.2.3.1.5.2U_L_DataContinue-Service

The U_L_DataContinue-Service transmits one byte containing an EIB-L_Data-Frame to the

TP-UART-IC. The index starts with 1 and the maximum value is 62 depending on the length

of the frame. But the EIB confirms just the length of 22 Bytes.

3.2.3.1.5.3U_L_DataEnd-Service

The U_L_DataEnd-Service marks the end of the transmission of the EIB frame. After

receiving this service the TP - UART controls the checksum and in case of correctness it

starts the transmission on the EIB, else the UART returns a state indication with receive-

error flag is set.
