Appendix 2. Application to Multi-Programmer
The S5U1C31001L1200 (Bridge Board Ver. 2) allows multi-programming
(*1)
using a J-Link. Multi-programming
uses the +5 V power output of the J-Link as the V
PP
ON/OFF control signal. This does not allow use of the +5 V as
the power source of this board. Therefore, multi-programming requires an external power supply (DC +5 V) to
drive this board and to change the jumper settings on this board.
When performing multi-programming using the MCU’s power voltage booster, this board is not required.
(*1) The flash memories of more than one S1C31 Family MCU can be programmed simultaneously using a J-Link and the J-Flash
flash programming software that comes with the J-Link. For more information, refer to “Multi-Programming Application
Notes.”

A2.1 How to Change Jumper Setting
[When the JP3, JP4, and JP5 are used for the first time]
To set JP3 and JP4 to Open, cut the center of their shorted pad patterns. To short JP5, solder the separated short
pads.
A2.2 ENVPP Signal
Multi-programming does not require the ENVPP signal. Therefore, it is not necessary to connect the ENVPP signal
of the target board to this board. This board is not affected even if the ENVPP signal is connected.
