24.4 Programming Environment
manipulation such as writing and erasing. To write the flash memory off-board, a dedicated program adapter (FA
series) is necessary.
24.5 Communication Mode
communication via CSI10 or UART60 of the 78K0/FE2.
(1) CSI10
The environment required for writing a program to the flash memory of the 78K0/FE2 is illustrated below.
A host machine that controls the dedicated flash memory programmer is necessary.
To interface between the dedicated flash memory programmer and the 78K0/FE2, CSI10 or UART60 is used for
Communication between the dedicated flash memory programmer and the 78K0/FE2 is established by serial
Transfer rate: 2.4 kHz to 2.5 MHz
