Note This is possible by selecting the entire memory area for the block erase function.
program command prohibit, read command prohibit, and boot block cluster rewrite prohibit functions are enabled by
default after shipment, and security settings can be specified only 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 erasure status of the entire memory is
checked.
The contents of the entire memory area
are erased all at once.
The contents of specified memory blocks
are erased.
Writing to specified addresses, and a
verify check to see if the write level is
secured, are performed.
Data read from the flash memory is
compared with data transferred from the
flash memory programmer.
Data written to the flash memory is read.
Use of the block erase command, chip
erase command, program command, and
read command, and boot area rewrite, are
prohibited.
Functional Outline
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 a block erase command on all blocks is prohibited. Setting of prohibition
can be initialized by execution of a chip erase command.
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 block clusters from block 0 to the specified last block can be protected. The
protected boot block clusters cannot be rewritten (erased and written). Setting of
prohibition cannot be initialized by execution of the chip erase command.
The following can be specified as the last block:
