CHAPTER 16 FLASH MEMORY
16.2 Memory Configuration
The 1/2/4 KB internal flash memory area is divided into 4/8/16 blocks and can be programmed/erased in block
units. All the blocks can also be erased at once, by using a dedicated flash memory programmer.

The internal flash memory of the 78K0S/KU1+ can be rewritten by using the rewrite function of the dedicated flash
memory programmer, regardless of whether the 78K0S/KU1+ has already been mounted on the target system or not
(on-board/off-board programming).
The function for rewriting a program with the user program (self programming), which is ideal for an application
when it is assumed that the program is changed after production/shipment of the target system, is provided.
Refer to Table 16-1 for the flash memory writing control function.
In addition, a security function that prohibits rewriting the user program written to the internal flash memory is also
supported, so that the program cannot be changed by an unauthorized person.
Refer to 16.7.3 Security settings for details on the security function.
