The PD78F0711 and 78F0712 support a self-programming function that can be used to rewrite the flash memory
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 a separate document to be published soon
