Settings of this jumper need to be changed according to the power
supply voltage and power supply condition of the user system. The
internal power supply is supplied to the evaluation MCU in factory
setting.
For details, refer to "2.10.2 "Setting the POWER Selection Jumper"
(page 39).
This jumper pulls the user system's RESET pin high with 510 kΩ.
Although settings of this jumper do not normally need to be
changed, if the 510 kΩ pullup presents a problem when the user
system is connected, the board may be used without this resistor
pullup.
