snvs_lp_srtc#
Overview#
The SNVS LP SRTC project is a simple demonstration program of the SDK SNVS LP driver. The test will set up secure RTC (SRTC) date and time to a predefined value and starts the counter, then the SRTC counter value is synchronized with non secure RTC (RTC). RTC then triggers an alarm after a user specified time period. The alarm will be set with reference to this predefined date and time.
