You can use the NFC BSP Module to set the NFCT peripheral as a wakeup source. It can be used with other BSP modules as long as their button configuration is not overwritten by this module.

The application must notify this module before going into System OFF mode. Based on this notification, the NFC BSP Module sets the NFCT peripheral as a wakeup source through the Board Support Package.

Additionally, the NFC Module can configure any BSP Button to generate BSP sleep events.
