19.6.1 Flash Memory Erasing Mode (Operating command: F0H)
Note 1: “xxH × 3” indicates that the device enters the halt condition after transmitting 3 bytes of xxh.
Note 2: Refer to " ".
Note 3: Refer to " 19.8 Checksum (SUM) ".
Note 4: Refer to " 19.10 Passwords ".
Note 5: Do not transmit the password string for a blank product.
Note 6: When a password error occurs, TMP88F846UG stops UART communication and enters the halt mode. Therefore, when a
