1.10.2 Flash Over USB Reprogramming (FOUSB)
M3A-8K02 enables “Flash Over USB” on-board programming of 38K0/38K2 Flash chips using the USB
function. To perform FOUSB (always make sure external power supply is disconnected), set the VCC-SELECT
switch (S7) and the BOOT-MODE switch appropriately, set the FLASH switch (S9) to ON, and then connect the
up-port to your computer. The FLASH lamp (4) will go on and the host will recognize operations with
“RENESAS Flash-Over USB.” After the host PC is connected, run the application program bundled with the
M3A-8K02 on the PC and follow the instructions for reprogramming the application firmware.
