2.18.12 Tamper Detection Timestamp
If an external Reset occurs during a tamper detection, the timestamp register will not be updated when the next tamper detection is triggered.
Work Around:
Enable RTC tamper interrupt and copy the timestamp from the RTC CLOCK COUNT register
to one of the following destinations:
- SRAM
- GPx register in RTC
- BKUPx register in RTC
Note: This work around does not apply for Battery Backup
mode. In Battery Backup mode, the RTC Timestamp capture feature is not
functional.
