20.6.7 Flash Memory security program Setting Mode (Operation Command: FAH)
Table 20-13 shows Flash memory security program setting mode process.
Note 1: “xxH
×
3” indicates that the device enters the halt condition after sending 3 bytes of xxH. For details, refer to " 20.7 Error
Note 2: Refer to " 20.10 Passwords ".
Note 3: If the security program is enabled for a blank product or a password error occurs for a non-blank product,
T5CL8
stops UART communication and enters the halt mode. In this case, initialize
T5CL8
by the
RESET
pin and reactivate the serial PROM mode.
Note 4: If an error occurs during reception of a password address or a password string,
T5CL8
stops UART communi-
cation and enters the halt mode. In this case, initialize
T5CL8
by the
RESET
pin and reactivate the serial PROM
mode.
Description of the Flash memory security program setting mode
1. The 1st through 4th bytes of the transmitted and received data contain the same data as in the Flash
memory writing mode.
2. The 5th byte of the received data contains the command data in the flash memory status output mode
(FAH).
3. When the 5th byte of the received data contains the operation command data shown in Table 1-6, the
device echoes back the value which is the same data in the 6th byte position of the received data (in
