POLLING AUTO WRITE (PW)
For POLLING AUTO WRITE, the ID Controller immediately returns a response informing the host
device that the command has been received (end code: 74 = polling command received). The ID
Controller then waits for a Data Carrier to approach and writes data to Data Carrier memory. During
this time, the host device can check on the result of the command processing by using a subcommand.
