If the EAS mode is disabled the ICODE SLIX IC remains silent.
9.4.3.11 PASSWORD PROTECT EAS/AFI
Command code = A6h
The PASSWORD PROTECT EAS/AFI command enables the password protection for
EAS and/or AFI if the EAS/AFI password is first transmitted with the SET PASSWORD
command.
Option flag set to logic 0: EAS will be password protected.
Option flag set to logic 1: AFI will be password protected.
Both password protections (AFI and EAS) can be enabled separately.
Remark: Independent of the Option flag, this write-alike command will be executed like a
write command with Option flag 0 (Option flag not set).
Once the EAS/AFI password protection is enabled, it is not possible to change back to
unprotected EAS and/or AFI.
