Pretransmit data exchange

Pretransmit automatically runs before any configured prefetch in the
PRECONNECTED link state, see Chapter 2.2.1 "SLK operating states".
The buffer mode of a selected transfer buffer indicates whether a single transmit
(buffer mode 2) or a multiple transmit (buffer mode 3) should be executed. The
data blocks designated for the MDT are entered consecutively in the corresponding
transfer buffer. The MDT addresses to which and length with which the individual
data blocks should be transferred is indicated in the buffer mapping.
It is also possible to only transmit one MDT data block with a transfer buffer for
better clarity. Up to four data blocks can be written in this manner.
If the buffer status value is 0x02, the data was entered in the MDT.
