Get System Info
When receiving the Get System Info command, the LRI2K 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 LRI2K provides 64 blocks (3Fh) of 4 bytes (03h).
IC Reference. Only the 6 MSBs are significant. The product code of the LRI2K is
00 1000b=8d
Response parameter:
Error Code as Error_Flag is set:
03h: Option not supported
0Fh: other error
