Get System Info
When receiving the Get System Info command, the M24LR64-R 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.
The Protocol_extention_flag should be set to 1 for the M24LR64-R to operate correctly. If
the Protocol_extention_flag is at 0, the M24LR64-R answers with an error code.
