Note 1: "0x** × 3" means that the device goes into an idle state after transmitting 3 bytes of 0x**. For further information, refer to
Note 2: For information on checksums, refer to "22.10 Checksum (SUM)". For information on passwords, refer to "22.12.1 Pass-
Note 3: If the area 0xFFE0 through 0xFFFF is all 0xFF, password authentication is not performed and, therefore, the password
Note 4: If the security program is enabled in flash memory or if a password error occurs, the TMP89FM42L stops communication,
Note 5: If a communication error occurs during the transfer of a password address or a password string, the TMP89FM42L stops
Note 6: If the number of bytes received at the m-th + 7 byte, m-th + 9 byte or m-th + 11 byte is more than 0x000000 or the size

string need not be transmitted. The password count storage address and password comparison start address, however,
must be specified, even for a blank product. If the password count storage address and/or password comparison start
address are/is incorrect, a password error occurs; the TMP89FM42L stops communication and goes into an idle state.
Therefore, if a password error occurs, initialize the TMP89FM42L by using the RESET pin, and restart the serial PROM
mode.
