57 / 90 page ![]() Table 105. Set EAS response when Error_flag is NOT set Response SOF Response flags CRC16 request EOF - 8 bits 16 bits - Response parameter: • No parameter Table 106. Set EAS response when Error_flag is set Response SOF Response flags Error code CRC16 request EOF - 8 bits 8 bits 16 bits - Response parameter: • Error code as Error_flag is set – 03h: command option is not supported – 12h: the EAS configuration cannot be changed as eith the security session is closed, or locked – 13h: the EAS configuration was not successfully programmed 6.4.25 Reset EAS The Reset EAS command is used to deactivate the EAS if the EAS feature is not locked nor protected by the configuration password. If the EAS mode is locked, the Reset EAS command will be ignored, and the ST25TV02K/512 respond with an error. When the EAS mode is not locked: • If the EAS mode is not protected by password, the Reset EAS command will clear the EAS mode. • If the EAS mode is password protected the configuration password has to be first transmitted with the PRESENT PASSWORD command. Then the reset EAS command can be executed, and will clear the EAS mode • If the EAS mode is password protected, but the PRESENT PASSWORD has not been transmitted before or not successful, the reset EAS command is not executed and the ST25TV02K/512 respond with an error Table 107.
