The RTCC provides the user with a Real-Time Clock
and Calendar (RTCC) function that can be calibrated.
Key features of the RTCC module are:
• Operates in Deep Sleep mode
• Selectable clock source
• Provides hours, minutes and seconds using
• Visibility of one half second period
• Provides calendar – weekday, date, month and

The user can select between the SOSC crystal
oscillator or the LPRC internal oscillator as the clock
reference for the RTCC module. This is configured
using the RTCCKSEL (FDS<5>) Configuration bit. This
gives the user an option to trade off system cost,
accuracy and power consumption, based on the overall
system needs.
