This command works in the same way as a normal write command. Once writing
is completed, the data from before the overwriting process is protected, providing
that the read/write tags offer this function.
This applies for 21, 22, 24 and 33 type 13.56 MHz read/write tags as well as for
IDC-...-1K LF read/write tags. Write protection is only activated for memory blocks
involved in the writing process. Data can continue to be written to all other
memory blocks.
The read/write head makes one attempt to write <WordNum> 32-bit words from
the address <WordAddr>.
