register (FLPMC).
The 78K0/KE1+ supports a self-programming function that can be used to rewrite the flash memory via a user
The programming mode is selected by bits 0 and 1 (FLSPM0 and FLSPM1) of the flash programming mode control
The procedure of self-programming is illustrated below.
Remark For details of the self programming function, refer to the 78K0/Kx1+ Flash Memory Self Programming
