Micro RWD H1/S Protocol
The MicroRWD H1/S Reader mode is a complete read / write and tag acceptance solution for
Hitag 1, Hitag S256 and Hitag S2048 RFID transponders (in Plain Memory mode).
Write Tag Page
Command to write 4 bytes of data to HT1 32 bit page. If the write was unsuccessful (invalid
tag or out of field) then Status flags in acknowledge byte indicate error.

Write Tag Block
Command to write up to 16 bytes of data to HT1 memory. A Block is made up of four pages
(each page being 4 bytes of data). If the specified page lies on the block boundary then all 16
bytes (4 pages) can be written. If the specified page is on the block boundary + 1 then 12
bytes (3 pages) can be written.
In this way 16, 12, 8 or 4 bytes of data can be stored on the tag depending on the page number
and it’s position within the block. If the write was unsuccessful (invalid tag or out of field)
then Status flags in acknowledge byte indicate error.

| Up to 16 bytes can be specified depending on page address N
| ie. Perform PAGE/4 => if remainder (mod) = 0 then full block (16 bytes)
| if remainder = 1 then 12 bytes sent
| if remainder = 2 then 8 bytes sent
| if remainder = 3 then 4 bytes sent
