3.3.5.
Sets the selected transponder in halt mode, i.e. the transponder is muted until it has left the RF
field or until the RF field is deactivated. By using this command different transponders can be han-
dled simultaneously in the operating field of the antenna.

3.3.6.
Reads a page of the selected transponder.
The command “ReadPage_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 “ReadPage_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.
