39 Semiconductors ICODE SLI Commands Remarks Only Option 0 (option flag is not set) is supported by ICODE SLI at the following commands: Write single block Lock block Write AFI Write DSFID Lock DSFID Option flag is not set: The Label shall return it’s response when it has completed the write/lock operations (time is specified in the ISO)

40 Semiconductors Response Flags & Error Flags ICODE SLI The ‘Response’ Flags indicate how actions have been performed by the Label! Response Flags if No Error occurred  ‘0x00’ Response Flags if an Error occurred  ‘0x01’ Response Data Error Code  ‘0x0F’ … means acc. To ISO: Error with no information given or a specific error code is not supported. Philips does not support specific error codes Remark: Only addressed Labels resp. selected Labels should respond with an error code. At unadressed commands the Labels have to remain silent if an error occurs!
