Receive buffer entry (MSB first) consisting of label data and additional data containing the
entry error flag (AE). If bit 31 is interpreted as error bit or data bit can be setup by the
command Api429CmdRxIni().
Note: The amount of label data words to read from the receive buffer of the selected
label should correspond to the "label receive buffer size (w_BufSize)" in
the "Api429CmdRxLabCon command".
Note: If the Loop/Pollution mode is enabled via the function Api429CmdRxIni, the
value represents the data that has been received before it is polluted!!!
