Configuration Byte 0:
Configuration Byte 0 / Bit 7:
Bit= ‘1’: Logdata can be read and written to.
Bit= ‘0’: Logdata cannot be accessed.
This bit can be set or reset until Bit 4 of Configuraion Byte 1 is set to ‘0’.
For further information on Logdata and Keys see chapter „Personalization“.
Configuration Byte 0 / Bit 6:
Bit= ‘1’: Keys can only be written to.
Bit= ‘0’: Keys cannot be accessed.
This bit can be set or reset until Bit 4 of Configuration Byte 1 is set to ‘0’.
For further information on Logdata and Keys see chapter „Personalization“.
Configuration Byte 0 / Bits 0 ... 5:
If one of these Configuration Bits reads ‘1’, the corresponding block of the transponder can be
read and written.
If the bit is set to ‘0’, the corresponding block can only be read.
Within one block the configuration is always identical, that means either all 4 pages are read/write
or all of them are read only.
These bits can be set or reset until Bit 4 of Configuration Byte 1 is set to ‘0’.
