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.
