Note:
offers these four commands, of which the details are provided on the following subsections.
If a password is set to 0xFF (erased data), it is difficult to protect data securely due to an easy-to-guess
password. Even if Single Boot mode is not used, it is recommended to set a unique value as a password.
When Single Boot mode is selected, the boot program is automatically executed on startup. The boot program

RAM and executes the program once the transfer is successfully completed. The user program RAM
space can be assigned to the range from 0x2000_0400 to the end address of RAM, whereas the boot
program area (0x2000_0000 ~ 0x2000_03FF) is unavailable. The user program starts at the assigned
RAM address.
this provides the ability to control on-board programming of the flash memory in a unique manner. The
programming routine must utilize the flash memory command sequences described in Section 15.3.
Before initiating a transfer, the RAM Transfer command verifies a password sequence coming from
the controller against that stored in the flash memory.
boot program does not provide a command to read out the contents of the flash memory. Instead, the
Flash Memory SUM command can be used for software revision management.
and the like. This command also reads out the contents of the flash memory locations at addresses
shown below. In addition to the Show Flash Memory Sum command, these locations can be used for
software revision management.
All the blocks in the memory cell and their protection conditions are erased even when any of the blocks
are prohibited from writing and erasing. When the command is completed, the FCSECBIT <SECBIT>
bit is set to "1". This command serves to recover boot programming operation when a user forgets the
password. Therefore password verification is not executed.
The RAM Transfer command stores program code transferred from a host controller to the on-chip
The RAM Transfer command can be used to download a flash programming routine of your own;

This command erases the entire area of the flash memory automatically without verifying a password.
