8.1.3.15 Lock EAS
Command Code = A4h
This command locks the current state of the EAS mode and the EAS ID. If the EAS mode
is password protected the EAS password has to be transmitted before with the Set
Password command.

8.1.3.16 EAS alarm
Command Code = A5h
The EAS Alarm command can be used in the following three configurations:
• Option flag is set to 0:
EAS ID Mask length and EAS ID value shall not be transmitted
If the EAS mode is set the EAS response is returned from the
I•CODE
SLI-S/I•CODE SLI-S HC IC. This configuration is compliant to the EAS
command of the ICODE SLI IC.
• Option flag is set to 1:
Within the command the EAS ID Mask Length has to be transmitted to identify how
many bits of the following EAS ID value are valid (multiple of 8-bits). Only those
I•CODE
SLI-S/I•CODE SLI-S HC ICs will respond with the EAS response which have
stored the corresponding data in the EAS ID configuration (selective EAS) and if the
EAS Mode is set.
If the EAS ID Mask length is set to 0, the I•CODE SLI-S/I•CODE SLI-S HC IC will
answer with its EAS ID.
