26.4 Programming Environment

The environment required for writing a program to the flash memory of the 78K0/KE2 is illustrated below.
Figure 26-5. Environment for Writing Program to Flash Memory
Host machine
A host machine that controls the dedicated flash programmer is necessary.
To interface between the dedicated flash programmer and the 78K0/KE2, CSI10 or UART6 is used for
manipulation such as writing and erasing. To write the flash memory off-board, a dedicated program adapter (FA
series) is necessary.

26.5 Communication Mode

Communication between the dedicated flash programmer and the 78K0/KE2 is established by serial
communication via CSI10 or UART6 of the 78K0/KE2.
