Configuration Byte 0:

Configuration Byte 0 / Bit 7:

Bit 7 = ‘1’: Logdata can be read and written to.

Bit 7 = ‘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 “Definition of Keys and Logdata“.

Configuration Byte 0 / Bit 6:

Bit 6 = ‘1’: Keys can only be written to.

Bit 6 = ‘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 “Definition of Keys and Logdata“.

Configuration Byte 0 / Bits 0 ... 5:

If one of these Configuration Bits is ‘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’.
