Data verification failed
If the command sequence is validated and the addressed block is not write-protected, the new
data will be programmed into the EEPROM memory. The new state of the block-write protec-
tion bit (lock bit) will be programmed at the same time accordingly.
Each programming cycle consists of 4 consecutive steps.

Reset
1. Erase block
2. Erase verification (data = “0”)
3. Programming
4. Write verification (corresponding data bits = “1”)
• If a data verification error is detected after an executed data block programming, the tag will
stop modulation (modulation defeat) until a new command is transmitted.
