Get System Info
When receiving the Get System Info command,
the LRI64 send back its information data in the Re-
sponse.The Option_Flag is supported and must
be set to 0. The Get System Info can be issued in
both addressed and non addressed modes.
The Request Frame (
Figure 26.
) contains:
Request Flags (
Table 3.
and
Table 4.
)
Get System Info Command Code (2Bh,
Table
9.
)
Unique ID (Optional)
2-byte CRC (
Figure 15.
)
If there is no error, at the LRI64, the Response
Frame (
Figure 27.
) contains:
Response Flags (
Table 6.
)
Information Flags set to 0Fh, indicating the
four information fields that are present
(DSFID, AFI, Memory Size, IC Reference)
Unique ID
DSFID value (as written in block 9)
AFI value (as written in block 8)
Memory size: for the LRI64, there are 15
blocks (0Eh) of 1 byte (00h).
IC Reference: only the 6 most significant bits
are used. The product code of the LRI64 is
00 0101

d
2-byte CRC (
Figure 15.
)
Otherwise, if there is an error, the Response
Frame (
Figure 28.
) contains:
Response Flags (01h,
Table 6.
)
Error Code (0Fh,
Table 7.
)
2-byte CRC (
