3.7 Switches

The following switches are available on the WBZ450 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 WBZ450PE Module.

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