The RTC_C module can be configured for real-time clock or calendar mode that provides seconds, hours, day of week, day of month, month, and year. The RTC_C control and configuration registers are password-protected to ensure clock integrity against runaway code. Calendar mode integrates an internal calendar that compensates for months with less than 31 days and includes leap year correction. The RTC_C also supports flexible alarm functions, offset calibration, and temperature compensation. The RTC_C on this device operates on dedicated AUXVCC3 supply and supports operation in LPM3.5.
