Command 06 instructs the controller to write information to an RFID tag. This command
is used to store segments of data in contiguous tag memory locations. It is capable of
transferring up to 100 bytes of data from the host to the tag with one command.
The shortest possible Write Length is one (0x0001). When the Start Address is set to
zero (0x0000), the controller will begin writing to the first available byte of tag memory.
The Timeout Value is measured in 1-millisecond increments and can have a value of
0x0001 to 0xFFFE (1 to 65,534 milliseconds). If the Write Length exceeds beyond the
last available tag address, the controller will return an error code.
