Ending command repetition
You have the option of ending command repetition by resetting "RPTCMD" or using the
"INIT" or "SRESET" commands. The various procedures are described below
End the Repeat command and reset "RPTCMD":
1. Reset the "RPTCMD" input parameter.
2. Fetch any existing acknowledgments using the "EXECUTE" input parameter.
The "RPTACT" output parameter remains set by the reader as long as there are
acknowledgements present.
3. When there are no more acknowledgments, "RPTACT" is reset by the reader.
It is always possible to reset the Repeat command with a "RESET" ("INIT", "SRESET").
Figure 7-22
The "RPTACT" output parameter is reset by the reader. Under certain circumstances, it is
possible that resetting "RPTACT" will be delayed. In other words not at the same time as the
"DONE" of the last acknowledgement. If the block is now restarted with "EXECUTE" and
"RPTACT" is still set although there are no longer any results in the buffer, the block is not
ended (BUSY = 1). In this case, you can wait until the next transponders are read out. As an
alternative, the block can be ended with "INIT" or "SRESET".
