units. All the blocks can also be erased at once, by using a dedicated flash memory programmer.
14.3 Functional Outline
the dedicated flash memory programmer, regardless of whether the PD78F9500, 78F9501, 78F9502 have already
been mounted on the target system or not (on-board/off-board programming).
when it is assumed that the program is changed after production/shipment of the target system, is provided.
supported, so that the program cannot be changed by an unauthorized person.
The 1/2/4 KB internal flash memory area is divided into 4/8/16 blocks and can be programmed/erased in block
The internal flash memory of the PD78F9500, 78F9501, 78F9502 can be rewritten by using the rewrite function of
The function for rewriting a program with the user program (self programming), which is ideal for an application
Refer to Table 14-1 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
Refer to 14.7.3 Security settings for details on the security function.
