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 programmer.
The erasure status of the entire memory is
checked.
Use of the block erase command, chip
erase command, program command, and
read command is prohibited, and rewriting
of the boot area is prohibited.
Functional Outline
Execution of write, block erase, and chip erase commands on the boot area is prohibited.
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.
Setting of the prohibition of rewriting the boot area cannot be initialized after it is once set.
