Get System Info
When receiving the Get System Info command, the M24LR04E-R sends back its information
data in the response.The Option_flag is not supported. The Get System Info can be issued
in both Addressed and Non Addressed modes.
The Protocol_extension_flag must be set to 0.
to the Get System Info command depending on the value of the Protocol_extension_flag.
