Command Data
The eight commands shown in Table 15-6 are used in the serial PROM mode. After reset release, the

tor erase in the flash erasing mode can not be performed. To disable the security program, perform the

TMP86FH46BNG calculates the checksum for the entire flash memory area (C000H to FFFFH), and re-
turns the obtained result to the external controller. When the security program is enabled, the flash memo-
ry writing mode is not activated. In this case, perform the chip erase command beforehand in the flash mem-
ory erasing mode. Before activating the flash memory writing mode, TMP86FH46BNG checks the pass-

ting the results, the RAM loader jumps to the RAM address specified with the first data record in order
to execute the user program. When the security program is enabled, the RAM loader mode is not activa-
ted. In this case, perform the chip erase beforehand in the flash memory erasing mode. Before activating
the RAM loader mode, TMP86FH46BNG checks the password except a blank product. If the password
is not matched, flash RAM loader mode is not activated.

Erases the flash memory area (address C000H to FFFFH).
Writes to the flash memory area (address C000H to FFFFH).
Writes to the specified RAM area (address 0050H to 023FH).
Outputs the 2-byte checksum upper byte and lower byte in this order for
the entire area of the flash memory (address C000H to FFFFH).
Outputs the product ID code (13-byte data).
Outputs the status code (7-byte data) such as the security program condi-
tion.
Enables the security program.
