TMP89FS60

RA002

Note 1: "0x**

× 3" means that the device goes into an idle state after transmitting 3 bytes of 0x**. For further information, refer to

Table 22-18.

Note 2: For information on checksums, refer to "22.10 Checksum (SUM)". For information on passwords, refer to "22.12.1 Pass-

words".

Note 3: If the area 0xFFE0 through 0xFFFF is all 0xFF, password authentication is not performed and, therefore, the password

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 TMP89FS60 stops communication and goes into an idle state.

Therefore, if a password error occurs, initialize the TMP89FS60 by using the RESET pin, and restart the serial PROM

mode.

Note 4: If the security program is enabled in flash memory or if a password error occurs, the TMP89FS60 stops communication,

and goes into an idle state. Therefore, if a password error occurs, initialize the TMP89FS60 by using the RESET pin, and

restart the serial PROM mode.

Note 5: If a communication error occurs during the transfer of a password address or a password string, the TMP89FS60 stops

communication and goes into an idle state. Therefore, when a password error occurs, initialize the TMP89FS60 by using

the RESET pin, and restart the serial PROM mode.

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 of

internal memory, the TMP89FS60 stops communication and goes into an idle state.
