This function is utilized to read the status of a specific label transfer on the selected
API429 transmitter channel including timetag information (if setup with
Api429CmdTxXferDef)
Note: "pl_XferCnt" is cleared, whenever the "Api429CmdTxStart command" is
issued.
Note: For "label transfer data mode = discrete transfer mode" (see
"Api429CmdTxXferData command") the "pl_XferData" will be the label number
and the mask for the discrete register.
Note: For NOP transfers all output data except "pl_XferIx" will be returned with value
0.
