Hitag 1 Configuration Bytes
The Hitag 1 transponder mode and whether the memory pages are locked or open for
read/write operations is controlled by the configuration bytes. These are bytes 0 and 1 of
Page 1 of the Hitag 1 memory. Note that bytes 2 and 3 of the configuration page are not used
and are currently available for read/write use.

Note that these configuration bits are OTP. Once they are set to read-only the Hitag 1
transponder is hardware protected and they can never be changed.
Note that the “Reserved” bits of Configuration Byte 1 must not be altered. The current value
of byte 1 must be read first and the bits that can be changed, masked on before writing back.
