If the EAS mode is password protected the EAS password has to be transmitted before with the Set Password command. Table 52. Request format SOF Flags Lock EAS IC Mfg code UID CRC16 EOF 8 bits 8 bits 8 bits 64 bits optional 16 bits 8 bits Table 53. Response format when Error_flag is set SOF Flags Error code CRC16 EOF 8 bits 8 bits 16 bits Table 54. Response format when Error_flag is NOT set SOF Flags CRC16 EOF 8 bits 16 bits 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. Table 55. Request format SOF Flags EAS Alarm IC Mfg code UID EAS ID Mask Length EAS ID Value CRC16 EOF 8 bits 8 bits 8 bits 64 bits optional 8 bits optional 0, 8 or 16 bits optional 16 bits 8 bits If an error is detected the I•CODE SLI-S/I•CODE SLI-S HC IC remains silent. |
