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
