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 not supported and
must be set to 0. The Get System Info can be is-
sued in both addressed and non addressed
modes.
The Request Frame (Figure 27.) contains:
–
Request Flags (Table 3. and Table 4.)
–
Get System Info Command Code (2Bh, Table
9.)
–
Unique ID (Optional)
–
2-byte CRC (Figure 16.)
If there is no error, at the LRI64, the Response
Frame (Figure 28.) 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 16.)
Otherwise, if there is an error, the Response
Frame (Figure 29.) contains:
–
Response Flags (01h, Table 6.)
–
Error Code (0Fh, Table 7.)
–
2-byte CRC (Figure 16.)
