and program command prohibit functions are enabled by default after shipment, and security can be set by rewriting
via on-board/off-board programming. Each security function can be used in combination with the others at the same
time.

Function
Function
The contents of specified memory blocks
are erased.
The contents of the entire memory area
are erased all at once.
Writing to specified addresses, and a
verify check to see if write level is secured
are performed.
Data read from the flash memory is
compared with data transferred from the
flash memory programmer.
The erasure status of the entire memory is
checked.
Use of the block erase command, chip
erase command, program command, and
read command can be prohibited, and
rewriting boot area can be prohibited.
Functional Outline
Execution of a block erase command on all blocks is prohibited. Setting of prohibition
can be initialized by execution of a chip erase command.
Execution of block erase and chip erase commands on all the blocks is prohibited. Once
prohibition is set, setting of prohibition cannot be initialized because the chip erase
command cannot be executed.
Execution of program and block erase commands on all the blocks are prohibited.
Setting of prohibition can be initialized by execution of the chip erase command.
Execution of read command on all the blocks is prohibited. Setting of prohibition can be
initialized by execution of the chip erase command.
Boot areas from block 0 to the specified last block can be protected. The protected boot
area cannot be rewritten (erased and written). Setting of prohibition cannot be initialized
by execution of the chip erase command.
