3) FIFO Trigger
The Reader Writer will communicate with Tag immediately after
receiving command and transmit response. After transmission is
completed, the Reader Writer will prohibit Tag from operating. The
Reader Writer will be on stand by for commands after response is
transmitted. During transmission with Tag, there MUST BE AN
OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the transmission area. When this command is
executed, the Reader Writer automatically activates "Oscillation Mode"
♦ Operation Sequence
Upon receiving command, the Reader Writer will execute process once
only. If there is no Tag, a Tag absence error will be transmitted. During
processing of the command, Tag will become inoperative, and thus Tags
that have completed transmissions will not respond to the next command.
Oscillation will continue after command is processed.

4) FIFO Auto
The Reader Writer will await Tag to approach after receiving command,
then communicate with Tag and transmit response. After transmission is
completed, the Reader Writer will prohibit Tag from operating. The
Reader Writer will be on stand by after response transmission is
completed. During transmission with the Tag, there MUST BE AN
OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the transmission area. When this command is
executed, Module automatically activates "Oscillation Mode."
♦ Operation Sequence
After receiving command, the Reader Writer waits for the Tag to
approach, then executes process once only after Tag is detected. During
processing of the command, Tag will become inoperative, and thus Tags
that have completed transmissions will not respond to the next command.
Oscillation will continue after command is processed. When the Reader
Writer receives a STOP command, the command will be completed.
However, oscillation after completion of command continues.
