Writes a block (up to 4 pages) of the selected transponder.
Writing to encrypted areas of the HITAG 1 transponder with this command leads to a status
“NOTAG error“ and the transponder is reset.
To write to encrypted areas of the transponders use the command “WriteBlock_HT1_C“.
Access to the secret area is only possible in Crypto Mode after a mutual authentication.
With the command ”WriteBlock_HT1_P“ resp. ”WriteBlock_HT1_C“ data beginning from the
start address ( page number ) till the end of the block can be written. Depending on the start ad-
dress 4, 8, 12 or 16 Bytes are written with one command to the transponder.
Upon completion of the write command, a “Read after Write“ procedure should be carried out in
order to check whether the write access was successful.
