Note 1: “xxH × 3” indicates that the device enters the halt condition after transmitting 3 bytes of xxh.
Note 2: Refer to "21.13 Specifying the Erasure Area".
Note 3: Refer to "21.8 Checksum (SUM)".
Note 4: Refer to "21.10 Passwords".
Note 5: Do not transmit the password string for a blank product.
Note 6: When a password error occurs, TMP88FW45AFG stops UART communication and enters the halt mode. Therefore, when
