Get System Info
When receiving the Get System Info command, the LRI64 send back its information data in
the response.The Option_Flag is not 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 0101b=5d
●
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 (Figure 15)
