* Based on this notification, the NFC BSP Module sets the NFCT peripheral as a wakeup source
* through the Board Support Package. Additionally, any BSP Button can be configured to
* generate BSP sleep events. This module is applicable only if NFCT is used exclusively for
* wakeup. If NFCT is used for a different purpose, this module cannot be used.
