Figure 3: DL_DATA_SLAVE.indication transaction
The same transaction, in case the acknowledge (the same applies in case the
–indication
is lost) is lost, is the one depicted in the next figure, where the second
DL_DATA_SLAVE.indication message frame uses 0x03 as start of the frame byte instead
0x02 as the first one, to let the host controller check if the message has already been
received or not.
