9.13.5 Real-Time Clock (RTC_C)

The RTC_C module contains an integrated real-time clock (RTC) with the following features:

  • Calendar mode with leap year correction
  • General-purpose counter mode

The internal calendar compensates for months with fewer than 31 days and includes leap year correction. The RTC_C also supports flexible alarm functions and offset-calibration hardware. RTC operation is available in LPM3.5 modes to minimize power consumption.
