71 / 102 page ![]() LRIS2K Get System Info 71/102 34 Get System Info When receiving the Get System Info command, the LRIS2K sends back its information data in the request.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 LRIS2K provides 64 blocks (3Fh) of 4 byte (03h) ● IC Reference. Only the 6 MSB are significant. The product code of the LRIS2K is 00 1010b=10d Response parameter: ● Error code as Error_flag is set: – 03h: Option not supported – 0Fh: other error Table 59.
