  • Page 7: Usb Peripheral Power

    BMD-34 EVK - User guide 2.1.2 USB peripheral power VBUS Power from the USB Peripheral interface on the BMD-340 may be used to power the BMD-340-EVAL by moving SW7 to the “HV” setting. This enables the internal high-voltage regulator (LDO or DC-DC). When in the HV setting, the power switch SW6 should be left in the OFF position, especially if any of the protection diodes are bypassed.
  • Page 8 BMD-34 EVK - User guide When the reset button is directly connected to P0.18, it can be used as a fifth user button or as a reset button directly connected to the BMD-34 module. Solder jumper J18 is used to connect P0.18 of the BMD-34 module to the RESET_N net (noted as nRESET in Figure 4 below).

  • Page 9: Buttons

    BMD-34 EVK - User guide 2.3 Buttons The evaluation board has four user buttons: Button 1, Button 2, Button 3, and Button 4. All buttons are active low; they will connect to ground when pressed. The button GPIO pins must be configured with internal pull-up resistors for proper operation when using the user buttons.
