Communications Method Section 5-8

5-8-2-2 Auto Mode
In auto mode, after receiving an Auto command from the host, the Reader/Writer waits for a Tag to
enter the Antenna’s communications area. Since the Reader/Writer is in a busy state between Auto
command reception and the completion of communications with the Tag, it does not accept any
commands other than the Stop or Reset Command during the period.
