Serial Writing; Installation Of Mcu On Daughter Board; Setting For Serial Writing; Setting For Pc/Usb/Ydc Writer Switchove - Fujitsu BBF2004 Series Instruction Manual

3. Serial Writing

(1) Do not connect the MCU to the IC socket or disconnect it from that socket with the power
of this board turned on; otherwise, the host computer, this board, peripheral debugging
device, or MCU may be destroyed or emit smoke or catch fire. The user programs being
evaluated may also be destroyed.
(2) Be very careful about the direction in which the MCU is mounted. If the direction is incorrect,
the MCU, this board, or peripheral debugging device may be destroyed or emit smoke or
catch fire.
By using this board and a FUJITSU MICROELECTRONICS FLASH MCU Programmer (hereinafter
called the PC writer) or FUJITSU MICROELECTRONICS FLASH USB Programmer (hereinafter
called the USB writer) or Yokogawa Digital Computer serial writer (hereinafter called the YDC
writer), serial writing to the on-board MCU is enabled.
(Note)
Usage of PC writer: Connect a RS232C cable
Usage of USB writer: Connect a BGM connector
When the YDC writer is used, the power can be supplied to the MCU from the main board, but not
from the YDC. Be careful not to connect PC writer, USB writer and PC writer at the same time.
For information about the PC writer and USB writer, contact Fujitsu Microelectronics Limited. For
information about the YDC writer, contact Yokogawa Digital Computer Corporation.
3.1 Installation of MCU on the daughter Board
When the MCU is mounted on the IC socket, confirm that the MCU pins are straight. Then, mount
the MCU on IC socket "CS1" with the MCU No. 1 pin to the No. 1 pin mark "QFP 1PIN" on the
daughter board.

3.2 Setting for Serial Writing

For serial writing, the following three settings are required.
Make these settings correctly for the writing method to be used.
(1) Setting for PC/USB/YDC writer switchover
(2) Setting for MCU serial writing mode
(3) Setting for MCU writing program starting pins
3.2.1 Setting for PC/USB/YDC writer switchover
Set daughter board and main board appropriately for the writer to
be used.
(1) Setting for daughter board
Connect jumper pins "JP1"-"JP3" on the daughter board.
[When PC writer is used]
Connect jumper pins to 2-3 of "JP1" and "JP2" on the daughter
board with a jumper wire. (Figure 3-1)
[When USB/YDC writer is used]
Connect jumper pins to 2-3 of "JP1" to "JP3" on the daughter
board with a jumper wire. (Figure 3-2)
