Page 10: Usb Peripheral Power
The BMD-34x module has a configurable hardware reset. P0.18 is assumed to be used as the reset pin for all Rigado and Nordic example projects, and thus the evaluation board hardware is configured to use P0.18 as a reset. The Reset button can be configured to connect to an input on the interface IC or... -
Page 11: Figure 6 - Schematic - Reset
BMD-34x-EVAL User Guide Rev 2.0 The Reset button is connected to the IC used for the J-Link interface by default. Pressing reset while the interface IC is powered will caused a momentary reset signal on the nRESET output of the interface IC, which is connected via solder jumper to P0.18 of the BMD-34x module. -
