5.6.3 Command 6 (06 Hex): Block Write
DESCRIPTION
Write a block of data to an RFID tag.
DISCUSSION
The RF Port Block Write command is used to write segments of data
to contiguous areas of tag memory. It is capable of transferring up to
48 bytes of data. The timeout value is given in 1 msec increments and
can have a value of 1EH to FFFEH. A timeout of 0 will return a syntax
error.
The data to be written to the tag is contained in the LSB of the register,
and the MSB is always 00H.

Start Address The tag address where the write will start
Write Length The number of tag addresses to be written
