LVISTART
LVISTART can only be written by using a dedicated flash memory programmer. It cannot be set during
self-programming or boot swap operation during self-programming. However, because 0080H and 1080H
are switched during the boot swap operation, set a value that is the same as that of 0080H to 1080H.
To change the setting for the LVI default start, set the value to 0081H again after batch erasure (chip
erasure) of the flash memory. The setting cannot be changed after the memory of the specified block is
erased.
