prohibition/program command prohibition functions are enabled as the initial status after shipment; therefore, making
security settings is possible only by setting while rewriting via on-board/off-board programming using the dedicated
flash programmer. Security settings can be used in combination.

Remark
Function
×: Cannot be executed
: Can be executed
Executing the block erase command to all blocks is
prohibited. The prohibition setting can be initialized by
executing the chip erase command.
Executing block erasure on all blocks and the chip erase
command is prohibited. Once this prohibition function is
set, the chip erase command cannot be executed, so no
prohibition function can be initialized.
Executing a write command to all blocks and the block
erase command is prohibited. The prohibition setting
can be initialized by executing the chip erase command.
