Get System Info
When receiving the Get System Info command, the M24LR16E-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 can be set to 0 or 1. Table 70 and Table 72 show M24LR16E-R
response to the Get System Info command depending on the value of the
Protocol_extension_flag.
Request parameter:
●
Request flags
●
UID (optional)
Response parameters:
●
Information flags set to 0Ch. DSFID, AFI and IC reference fields are present.
●
UID code on 64 bits
●
DSFID value
●
AFI value
●
M24LR16E-R IC reference: the 8 bits are significant.
