Table 19-16 Password Setting in the Blank Product and Non-Blank Product
TMP86FH92DMG compares the data string specified to the password with the password string transmitted from the
external controller. The area in which passwords can be specified is located at addresses C000H to FF9FH. The area
from FFA0H to FFFFH can not be specified as the passwords area.

start address must be specified. Table 19-16 shows the password setting in the blank product and non-blank product.
The consecutive eight or more-byte data in the flash memory area can be specified to the password.
If addresses from FFE0H through FFFFH are filled with “FFH”, the passwords are not compared because the product
Note 1: When addresses from FFE0H through FFFFH are filled with “FFH”, the product is recognized as a blank product.
Note 2: The data including the same consecutive data (three or more bytes) can not be used as a password. (This causes a

Note 4: When the above condition is not met, a password error occurs. If a password error occurs, the device enters the halt
Note 5: In the flash memory writing mode or RAM loader mode, the blank product receives the Intel Hex format data immediately
Note 6: In the flash memory erasing mode, the external controller must not transmit the password string for the blank product.

after receiving PCSA without receiving password strings. In this case, the subsequent processing is performed correctly
because the blank product ignores the data except the start mark (3AH “:”) as the Intel Hex format data, even if the external
controller transmits the dummy password string. However, if the dummy password string contains “3AH”, it is detected as
the start mark erroneously. The microcontroller enters the halt mode. If this causes the problem, do not transmit the dummy
password strings.
