sequence simply do not acknowledge (NOACK) the last byte
received and the TMC2193 will terminate the sequence.
A repeated start signal occurs when the master device driv-
ing the serial interface generates a start signal without first
generating a stop signal to terminate the current communica-
tion. This is used to change the mode of communication
(read, write) between the slave and master without releasing
the serial interface lines.
