32 / 46 page ![]() MB89R119B 32 DS411-00002-4v0-E 2-12. Get System Information command On receiving the Get System Information command, the transponder returns the system information of UID, AFI, DSFID, etc. Request (from the reader/writer to the transponder) Response (from the transponder to the reader/writer) (1) When Error_flag set (2) When Error_flag not set The following table shows the definitions of the Information flag. The following figure shows the memory size information included in the response of the Get System Information. However, the block size and number of blocks in the user area shown in the memory size information about the transponder indicates one less than the actual value. Definition of information flag * : Reserved for future use Note : For MB89R119B set “0FH” (“1” for bit1 to bit4 and set “0” for bit5 to bit8) . Memory size information about a transponder * : Reserved for future use SOF Flags Command (Get System Information) UID (Addressed mode) CRC EOF 8 bits 8 bits (“2BH”) 64 bits 16 bits SOF Flags Error code CRC EOF 8 bits (“01H”) 8 bits 16 bits SOF Flags Information flags UID DSFID AFI Memory size IC reference CRC EOF 8 bits (“00H”) 8 bits 64 bits 8 bits 8 bits 16 bits 8 bits 16 bits Bit Flag name State Description 1 DSFID 0 DSFID is not supported or does not exist. 1 DSFID is supported or exists. 2 AFI 0 AFI is not supported or does not exist. 1 AFI is supported or exists. 3 Memory size 0 Memory size information is not supported or does not exist. 1 Memory size information is supported or exists. 4 IC reference 0 IC reference information is not supported or does not exist. 1 IC reference information is supported or exists. 5 RFU* Set to “0” 6 RFU* 7 RFU* 8 RFU* MSB LSB 16 14 13 9 8 1 RFU* Blocks size in bytes Number of blocks in user area |
