7.2.3 SPECIAL FUNCTIONS
The special functions block 3 (see Table 5) holds the two bits E (EAS mode) and two bits Q (QUIET mode). The
remaining 28 bits (marked X) are reserved for future use.
If the electronic article surveillance mode is active (bits EE = 11), then the label answers at an EAS command.
If the QUIET mode is enabled (setting bits QQ = 11), then the label is permanently disabled but can be activated again
with the command RESET QUIET BIT. The label can be activated also by disabling the QUIET mode by setting
bits QQ = 00. The state of the QUIET mode does not influence the functionality of the EAS command.
Writing of bit pairs 10 or 01 to block 3 is not allowed.
Remarks: Changing of the write access control or configuration must be done in a secure environment by reading the
current value of the block and masking in the new values for bit positions that may be changed. The label must not be
moved out of the communication field of the antenna during writing! We recommend to put the label close to the antenna
and not to remove it during operation.

7.2.4 FAMILY CODE AND APPLICATION IDENTIFIER
The I-CODE system offers the feature to use (independently) family codes and/or application identifiers with some reader
commands. This allows for example the creation of ‘label families’.
These two 8-bit values are located at the beginning of block 4 and are only evaluated if the bytes at the reader commands
are unequal to zero.
Only if both corresponding parameter bytes at the reader commands ANTICOLLISION/SELECT, EAS and
UNSELECTED READ respectively, are set to logic 0, then block 4 can be used for user data without restriction.
Bytes 2 and 3 are for customer usage.
