9.6.2.1 Value Blocks
9.6.1 Manufacturer block
9.6.2 Data blocks
This is the first data block (block 0) of the first sector (sector 0). It contains the IC
manufacturer data. This block is programmed and write protected in the production test.
Sectors 0 .. 31 contain 3 blocks and sectors 32 .. 39 contain 15 blocks for storing data.
(Sector 0 contains only two data blocks and the read-only manufacturer block).
The data blocks can be configured by the access bits as
An authentication command has to be carried out before any operation in order to allow
further commands.
The value blocks allow to perform electronic purse functions (valid commands: read, write,
increment, decrement, restore, transfer).The value blocks have a fixed data format which
permits error detection and correction and a backup management. A value block can only
be generated through a write operation in the value block format:
A value block can only be generated through a write operation in the value block format:

read/write blocks for e.g. contactless access control or
value blocks for e.g. electronic purse applications, where additional commands like
increment and decrement for direct control of the stored value are provided.
Value: Signifies a signed 4-byte value. The lowest significant byte of a value is stored
in the lowest address byte. Negative values are stored in standard 2´s complement
format. For reasons of data integrity and security, a value is stored three times, twice
non-inverted and once inverted.
Adr: Signifies a 1-byte address, which can be used to save the storage address of a
block, when implementing a powerful backup management. The address byte is
stored four times, twice inverted and non-inverted. During increment, decrement,
restore and transfer operations the address remains unchanged. It can only be
altered via a write command.
