Table 2.6.1 Flash Memory Writing Mode Process Note 1: “xxH × 3” denotes that operation stops after sending 3 bytes of xxH. For details, refer to 2.8 “Error Code”. Note 2: Refer to 2.10 “Intel Hex Format (Binary)”. Note 3: Refer to 2.9 “Checksum (SUM)”. Note 4: Refer to 2.11 “Passwords”. Note 5: If all data of vector area are “00H” or “FFH”, the passwords comparison is not executed because the device is considered as blank product. However, it is necessary to specify the password count storage addresses and the password comparison start address even though it is a blank product. If a password error occurs, the UART function of TMP86FS27 stops without returning error code to the controller. Therefore, when a password error occurs, the TMP86FS27 should be reset by RESET pin input. Note 6: The time between data records needs over 1 ms.
