Table 15-16 Password Setting in the Blank Product and Non-Blank Product
TMP86FH46BNG 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.
uct is considered as a blank product. Even in this case, the password count storage addresses and password compar-
ison start address must be specified. Table 15-16 shows the password setting in the blank product and non-blank prod-
uct.
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 prod-

“3AH”, it is detected as the start mark erroneously. The microcontroller enters the halt mode. If this causes the prob-
