EXPANSION WRITE (XW)
For EXPANSION WRITE, the ID Controller writes up to 2 KB to Data Carrier memory data by dividing
the data into frames. If there is no Data Carrier in the communications area, an error response with an
error code of 72 (Data Carrier missing) will be returned.
The host device cannot send commands to the ID Controller until all response frames have been
returned. (Excluding the AA command and XZ command.)
