Note
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
This is possible by selecting the entire memory area for the block erase 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 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 is prohibited. Setting of
prohibition can be initialized by execution of the chip erase command.
Execution of a read command on all of the blocks is prohibited. Setting of the prohibition can be
initialized by execution of a chip erase command.
Execution of write, block erase, and chip erase commands on the boot area is prohibited. Setting
of the prohibition of rewriting the boot area cannot be initialized after it is once set.
