Serial Programming Interface - Fujitsu Flash-64P-M01 Manual

1.5 Serial Programming Interface

The Flash memory of the MB90560/L series can be programmed in-circuit via the
serial UART1 interface. Therefore a special software PC frontend must be used
which is available on the Fujitsu Micros CD-ROM.
To prepare the evaluation board for the serial programming the following settings
must be done:
1. Power off the board
2. Connect the serial interface UART1 to your serial PC communication port.
Therfore a straight cable connection has to be used.
3. Set the mode and port pins to the serial asynchronous programming mode
(MD0, MD1, MD2 = 0,1,1; P01, P00 = GND). Shortcut RTS/CTS of the
UART1 interface.
Setting of the DIP switch S1:
S1 S2
ON OFF OFF OFF ON OFF ON ON
4. Power on the board
5. Check that the Reset LED is off. Otherwise change the DTR polarity and
check the power supply voltage.
6. Start the Flash programming software to download the program.
7. After downloading and programming of the Flash memory, switch off the
power supply and
set the mode and port pins according to the usage of the application:
e.g. single chip mode:
Setting of the DIP switch S1:
S1 S2
OFF OFF ON OFF OFF OFF OFF OFF
8. After power-on or Reset the user application is started directly.
In case of any errors check the following settings:
- Power supply (Jumpers J1, J7)
- Setting of DIP switch S1
- Connection of UART1 interface (Jumper J22, J23)
- Connection and polarity of DTR reset logic (Jumpers J9, J10)
