Following an echo-back of the command code, the boot program verifies the contents of the 12-byte
password area within the flash memory. The following table shows the password area.

(the 17th byte), regardless of whether the password sequence sent from the controller is all 0xFFs.
stored in the flash memory. All of the 12 bytes must match to pass the password verification. Otherwise, a
password error occurs, which causes the boot program to reply an error acknowledge in response to the
checksum byte (the 17th byte).
The RAM Transfer command (0x10) causes the boot program to perform password verification.
If all these address locations contain the same bytes of data other than 0xFF, a password area error
In this case, the boot program returns an error acknowledge (0x11) in response to the checksum byte
The password sequence received from the controller (5th to 16th bytes) is compared to the password
The password verification is performed even if the security function is enabled.
Password
Note: If a password is set to 0xFF (erased data), it is difficult to protect data securely to
due to an easy-to-guess password. Even if Single Boot mode is not used, it is
recommended to set a unique value as a password.
