8.31 RTC_B

The RTC_B instance of the real-time clock operates off of a 32kHz input clock source (typically a low frequency crystal) and provides a time base to the application with multiple options for interrupts to the CPU. The RTC_B provides common key features in relation to the Low-Frequency Sub System (LFSS).

Common key features of the RTC_B include:

  • Counters for seconds, minutes, hours, day of the week, day of the month, month, and year
  • Binary or BCD format
  • Leap-year handling
  • One customizable alarm interrupt based on minute, hour, day of the week, and day of the month
  • Interval alarm interrupt to wake every minute, every hour, at midnight, or at noon
  • Interval alarm interrupt providing periodic wake-up at 4096, 2048, 1024, 512, 256, or 128 Hz
  • Interval alarm interrupt providing periodic wake-up at 64, 32, 16, 8, 4, 2, 1, and 0.5 Hz
  • Calibration for crystal offset error (up to +/- 240ppm)
  • Compensation for temperature drift (up to +/- 240ppm)
  • RTC clock output to pin for calibration

Table 8-13 shows the RTC features supported in this device.
