The 4/8 KB internal flash memory area is divided into 16/32 blocks and can be programmed/erased in block units.
The internal flash memory of the 78K0S/KB1+ can be rewritten by using the rewrite function of the dedicated flash
The function for rewriting a program with the user program (self programming), which is ideal for an application
Refer to Table 19-1 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
