(6) Operation of Boot Program
When Single Boot mode is selected, the boot program is automatically executed on startup. The
boot program offers these three commands, of which the details are provided on the following
subsections. The addresses described in this section are the virtual unless otherwise noted.
1.
2.
3.
4. Chip and Protection Bit Erase command
Note: If a password is set to 0xFF (erased data), it is difficult to protect data securely to
This command serves to recover boot programming operation when a user forgets the
RAM Transfer command
The RAM Transfer command stores program code transferred from a host controller to the
on-chip 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.
The RAM Transfer command can be used to download a flash programming routine of your
own; 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 20.3.
coming from the controller against that stored in the flash memory.
Show Flash Memory Sum command
The Show Flash Memory Sum command adds the entire contents of the flash memory
together. The 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.
Show Product Information command
The Show Product Information command provides the product name, on-chip memory
configuration 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.
This command erases the entire area of the flash memory automatically without verifying a
password. 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”.
password. Therefore password verification is not executed.
Before initiating a transfer, the RAM Transfer command verifies a password sequence
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.
