3.3.7.
Reads a block (up to 4 pages) of the selected transponder.
The command “ReadBlock_HT1_P“ reads plain areas of the HITAG 1 transponders only.
Reading encrypted areas of the HITAG 1 transponder with this command leads to a status
“NOTAG error“ and the transponder is reset.
To read encrypted areas of the transponders use the command “ReadBlock_HT1_C“.
Access to the secret area is only possible in Crypto Mode after a mutual authentication.
In the “Advanced Protocol Mode“ of HITAG 1 transponders (by using the “GetSnr_HT1_Adv“-
command) the data is followed by an 8 Bit CRC.
With the command ”ReadBlock_HT1_P“ resp. ”ReadBlock_HT1_C“ data beginning from the
start address ( page number ) till the end of the block can be read. Depending on the start address
4, 8, 12 or 16 Bytes are provided by the reader module.
