memory. When the password string is not matched to the data in the flash memory, the device enters the halt
condition due to the password error.
serial PROM mode.
Therefore, it is recommended to use a fixed password in the program development stage.
The password string transmitted from the external controller is compared with the specified data in the flash
If a password error occurs, the device enters the halt condition. In this case, reset the device to reactivate the
If a program is modified many times in the development stage, confusion may arise as to the password.

Example
PNSA = F012H
PCSA = F107H
Password string = 01H,02H,03H,04H,05H
Example :Specify PNSA to F000H, and the password string to 8 bytes from address F001H
