62 / 90 page ![]() Table 124. Kill response format when Error_flag is set Response SOF Response_flags Error code CRC16 request EOF - 8 bits 8 bits 16 bits - Response parameter: • Error code as Error_flag is set – 03h: command option is not supported – 0Fh: error with no information given – 10h: block address not available – 14h: Kill mute mode could not be locked successfully 6.4.31 Write Kill Password On receiving the Write Kill command, the ST25TV02K/512 write the kill password (sent unencrypted) with the data contained in the request and reports whether the operation was successful in the response. The Option_flag is supported. After a successful write, the kill code must be locked by a Lock Kill command to activate the protection. During the write cycle tW, there should be no modulation (neither 100% nor 10%). Otherwise, the ST25TV02K/512 may not correctly program the data to the memory. The tW time is equal to t1nom +18 x 302 μs. Table 125.
