sidered as a blank product. Transmitting a password string is not required. Even in the case of a blank product, it is re-
quired to specify the password count storage address and the password comparison start address. Transmit these da-
ta from the external controller. If a password error occurs due to incorrect password count storage address or pass-
word comparison start address, TMP86FH46BNG stops UART communication and enters the halt condition. There-
fore, when a password error occurs, initialize TMP86FH46BNG by the RESET pin and reactivate the serial ROM mode.
