6 Using the Asynchronous Boot-Loader
The asynchronous boot-loader SW from Fujitsu can be used to program a blank flash
microcontroller. This tool is available on the floppy disc. The following additional steps to
chapter 5 need to be taken to set up the hardware (power supply disconnected!):
1. Place the flash microcontroller in its socket (observe pin no. 1 position).
2. Set DIP switch (SW3) :
1,5,7,8
ON
2,3,4,6
OFF
MB90470 / MB90480 series only:
1,5
ON
2,3,4,6,7,8
OFF
additionally Pin 47 and 48 (Port P80,P81) have to be connected to GND
for MB90470 and MB90480 series only (see chapter 5.1)
3. Switch on the power supply.
4. Start the asynchronous boot loader software and follow the instructions.
5. Set DIP switch (SW3)
for RUN-Mode,
e.g. Single-Chip-Mode

ON
1,2,4,5,6,7,8 OFF
MB90470 / MB90480 series only:
disconnect Pin 47 and 48 (Port P80,P81) from GND (see chapter 5.1)
6. Reset Target
