63 / 90 page  • Error code as Error_flag is set – 03h: command option is not supported – 10h: block address not available – 12h: the Kill access code is locked – 13h: the Kill access code was not successfully programmed 6.4.32 Lock Kill On receiving the Lock Kill command, the ST25TV02K/512 lock the Kill password permanently. The Option_flag is supported. During the write cycle tW, there should be no modulation (neither 100% nor 10%). Otherwise, the ST25TV may not lock the memory block correctly. The tW time is equal to t1nom + 18 x 302 μs. Table 128. Lock Kill request format Request SOF Request_fla gs Lock Kill IC Mfg code UID (1) Kill access Protect status CRC16 request EOF - 8 bits B2h 02h 64 bits 00h 01h 16 bits - 1. The field is optional. Request parameters: • Request flags • UID (optional) • Kill access code • Protection status Table 129. Lock Kill response format when Error_flag is NOT set Response SOF Response_flags CRC16 request EOF - 8 bits 16 bits - Response parameter: • No response: under unauthorized request flags and request parameters Table 130.

If not, the ST25TV does not answer to the Fast Inventory Initiated command. ST25TV02K ST25TV512 RF commands DS12074 - Rev 11 page 63/90 |
