User Buttons

Two user programmable buttons are available for use. These buttons are configured as pull-downs and are active high when pressed. The buttons are filtered with a pi filter to minimize transient effects.

There are multiple options for which pin functions mapped and are generally assigned to PTx/GPIO but note that SW2 does allow mapping to WKPU37 (wakeup) signal on the MCU and SW1 does allow mapping to CMP0 (comparator) signal on the MCU. These pin mux settings could be configured for interesting software use cases.
