HF5x Transponder Reader (SECS1-Protocol), Release 1.4
Reset is an optional service used to reinitialize the reader. If
reader parameter 9 is unequal to 0x00, the reset causes a S1F1
“Are you there” message from the reader.
The reader detects a wrong TARGETID

The TARGETID in the S18F5 message does not correspond to the
TARGETID in the reader detecting the error. The reader therefore
answers with a communication error “CE”.
