factory solidified user code 32 bytes write protection data area

security features:

1. Each byte of the write protection zone (the first 32 bytes) can be write protected separately. After write protection, the content cannot be changed (that is, solidified data)
2. Before the password is checked correctly, all data can be read. If necessary, the data can be properly encrypted.
3. After checking that the password is correct, it can be written or modified.
4. The user password of three bytes can be changed after being checked correctly, valid until the card is powered off.
5. Password error counter. The initial value is 3. If the password check error occurs once, it will be reduced by 1. If the counter value is 0, the card will be locked automatically and the data can only be read, no more changes can be made or password verification can be performed; If it is not zero, once the password verification is correct, it can be restored to the initial value.
6. Byte addresses 0-5, 6-7 have been written by the manufacturer before leaving the factory and cannot be changed.
