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. Following
If all these address locations contain the same bytes of data other than 0xFF, a password area error occurs
The password sequence received from the controller (5th to 16th bytes) is compared to the password stored
The password verification is performed even if the security function is enabled.
Note:If a password is set to 0xFF (erased data area), it is difficult to protect data securely due to an
