When supplying the power supply from AC adapter, TP2 (VCC) and TP3 (VSS) of the terminal for
an external power supply input should presuppose that it is open of it. Moreover, they must not sup-
ply an external power supply.
The details in the case of supplying a power supply from the terminal of an external power supply
input (TP2-TP8) are shown in Table 3.
When you supply the power supply from the terminals TP2 (VCC) and TP3 (VSS) for an external
power supply input, please set the jumper plug (JP3/JP4) of the power supply selection of 5V/3.3V
to opening, set SW2 (AC adapter power supply switch) to OFF, separate it completely, and use AC
adapter side power supply supply.

It is decided whether a light emitting diode connection change jumper plug (JP1/JP2) connects the
light emitting diode port on this board to each port of the evaluation MCU carried on the MCU board,
or it does not carry out.
When using a Light Emitting Diode port,an attached jumper plug is connected to this board. A jump-
er plug is not connected when not using a light emitting diode port.
About the switch of the state of the terminal of the evaluation MCU port corresponding to each light
emitting diode, lighting is deleted on L level. Moreover, lighting has H level given.
Correspondence of a Light Emitting Diode port is shown in Table 4.
