Reading from/Writing to Tags
POLLING AUTO WRITE (PW)
When the host device sends a POLLING AUTO WRITE command to the Controller, the Controller
immediately returns a response to the host device indicating reception of the command. Then the
Controller waits for the approaching Tag and writes the data when the Tag is in the communications
area.
When the Tag is in the communications area, the host device can use a subcommand to request the
command processing results. The host device can also send a command to another Read/Write Head.
