The 1/2/4 KB internal flash memory area is divided into 8/16 blocks and can be programmed/erased in block units.
The internal flash memory of the 78K0S/KY1+ 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
