Note:
J4 - Regulator Output Selection Jumper VOLT_EN
J5 - VDD Source Selection Jumper VDD_SELECT
The DEMOQE board power connector is incorrectly labelled as 5-12VDC.
The maximum voltage is 8VDC.
The regulator can output either a 2.1VDC or 3VDC voltage for the
DEMOQE128. The VOLT_EN jumper J4 selects the voltage. Figure 8-2
shows the regulator output selection details.

which derives its power from the USB bus
Select regulator input from the Embedded Multilink circuitry,
power supply must be used.
Select regulator output to be 2.1V.
Select regulator output to be 3V
Select the regulator to supply microcontroller VDD. This is the default
setting.
