3.2.3.1.12.3 TP-UART-State.indication/response Service
The TP-UART-State.response-service is sent if an U_State.request-Service was received from the
host. If the TP-UART is too hot (over-temperature), the TW-bit has the value 1. In case of Slave
Collision, Receive Error, Checksum Error or Protocol Error or Recognition Over-Temperature or
Recognition Leaving-Over-Temperature the TP-UART sends a State.indication-Service.

SC = Slave Collision
RE = Receive Error (Checksum, Parity or Biterror)
TE = Transmitter Error (send 0 receive 1)
PE = Protocol Error e.g. illegal controlbyte
TW = Temperature Warning
Attention: A received L-Data-Frame can follow the State indication without any delay.
3.2.3.1.12.4 TP-UART-L_Data.confirm Service
The L_DATA.confirm service is transmitted to the host if an acknowledge was received or if the last
repetition is transmitted and no acknowledge was received.
