If AckSeq = 0, segment transmitted was not received correctly and the segment must
be sent again.
If a processing error occurs at the controller an SDO error response to chap. 3.3.1.1,
p. 16 (e.g. timeout) is sent.
If the block transmission is aborted by the master, an abort SDO transfer telegram is
signalled (see chap. 3.3.3, p. 23).
