24 / 38 page ![]() LRI64 24/38 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.) Figure 35.
