3.9 Switches

The following switches are available on the WBZ451HPE Curiosity Board:

  • Reset switch (SW1)
  • User configurable switch (SW2)

In the Idle state, the level of the Reset switch is pulled high using the external pull-up resistor and, when the switch is pressed, it drives the level of the switch to low and resets the WBZ451HPE module.

The user-configurable switch is also pulled high using the external pull-up resistor. When the switch is pressed, it drives the level of the switch to low.
