62 / 86 page ![]() Commands codes LRI1K 62/86 Doc ID 17170 Rev 3 20.13 Get System Info When receiving the Get System Info command, the LRI1K sends back its information data in the response.The Option_flag is supported and must be reset to 0. The Get System Info can be issued in both Addressed and Non Addressed modes. Request parameter: ● UID (Optional) Response parameters: ● Information Flags set to 0Fh. DSFID, AFI, Memory Size and IC reference fields are present. ● UID code on 64 bits ● DSFID value ● AFI value ● memory size. The LRI1K provides 32 blocks (1Fh) of 4 bytes (03h). ● IC Reference. Only the 6 MSBs are significant. The product code of the LRI1K is 01 0000b=16d Response parameter: ● Error code as Error_flag is set: – 03h: Option not supported – 0Fh: other error Table 56.
