Jumpers And Switches; Power Supply (Jp3); User Leds (Jp1) - Fujitsu SK-8FX-TSC-32PMC User Manual

3 Jumpers and Switches

This chapter describes all jumpers and switches that can be modified on the evaluation
board. The default setting is shown with a grey shaded area.

3.1 Power Supply (JP3)

The SK-8FX-TSC-32PMC is by default powered by the USB connection to a host PC or USB
power supply. Alternatively, a stabilized supply voltage can be connected to the pin headers
X4 (GND) and X5 (VCC). JP3 must be opened in this case to disconnect the voltage
supplied by the USB connector X3.
JP3: Connects VCC to USB power supply

3.2 User LEDs (JP1)

Eight LEDs are supplied for user applications. In order to disable the LEDs e.g. to use the
related microcontroller port (Port P62-P67, P06-P07) for other connections, JP1 (solder
jumper) can be opened.
JP1: Enables User LEDs LD2-LD9 to VCC
